1) It depends on the situation.
In bot lane, I see a lot of Caitlyn Karma lanes, and you know that these lanes will constantly push because both of them have AOE abilities. So any one who's played League for some time should know this and know that this is a free gank lane. Same with a Yasuo or Riven and plenty of other champions. So when you're in a lane with a constantly pushing enemy who is an easy gank, it can be frustrating when your jungler decides it's better that his Lee Sin hard farms instead of ganking.
I had a game where I was autofilled top, so I picked Trundle and the enemy picked Nasus. I blew his flash early, so I bounced the wave and then froze it near my tower. I told my Rammus jungle he had no flash, but my jungler never came top despite a Nasus being pushed up to our tower. This is like the easiest gank in the world, but my jungler never came. Didn't matter if I got a good pillar cause he'd just wither me and I could never catch him, so we were literally just me getting a pillar and him withering and he'd get away with me only getting a hit or two in. If my jungler just came top once, we'd have a free kill. After me spam pinging the 200 hp Nasus literally dancing in the middle of my lane while my jungler did his top side buff did my midlaner finally roam top and take the free kill. In moments like that when it seems so obvious that your jungler should be here but they think they have to get blue first.
Now, if you mean that a lane is 0/4 and crying for jungler assistance, that's different. A jungler ignoring the losing lane in favor of helping a winning lane is ok. A farming jungler (Shyvana for example) farming instead of ganking is fine. However, if a lane is 0/1, that's no reason for a jungler to ignore that lane. Sometimes all the lane needs is for the jungler to appear once, even if the gank doesn't result in a kill, because it makes the enemy laner play more passively, or it lets the ally laner get the CS in the lane, which lets them complete and item and helps close the gap between the two. There was a game where I was jungle, and I decided to gank mid once cause we had a Leblanc (old LB) vs a Katarina. Leblanc got a kill and literally carried the game from there. I never returned to that lane but that one kill was enough to give her the advantage and let her snowball against Katarina. If Katarina's jungler had done that, perhaps Leblanc wouldn't have snowballed so hard. Or if he had ganked before I did, then Katarina might've taken over the game instead.
Sometimes one gank is all it takes to swing a lane, so that is why people just want some help from someone, and the jungler just happens to be blamed cause that's their role. Now, that's not to say it IS the junglers fault, but it can be really frustrating watching someone ignore what seems like a free kill when all you need is just a little help to get it.
2) Don't know. Unless they are autofilled and literally have no other champions that fit in that lane, I think it's mostly cause people think they are Faker and don't need to practice to be amazing.
3) This is mostly because people are more focused on winning over fun. If you hated Soraka, but knew that playing only Soraka meant you could get Challenger, I'm sure most people would jump on the chance for a guaranteed winning streak over playing something they enjoyed that was a possible loss. It's the same reason people take diet supplements or do strange diets when hoping to lose weight, they think it's a short cut and would rather have the result easily (quick weight loss or getting a Victory screen) over doing the work (exercise/eat healthy or learning to play League better) Most people think they are Plat+ and just being held back by their teammates, so any time their teammates do something dumb, it just triggers their confirmation bias and makes them upset cause their internal bias appears to be true (even though it's just a coincidence).
4) Same as above. People think they are being held back, so they get upset because of that instead of seeing their faults as well. You've probably had that game where you 0/5 ADC is solo splitpushing bot vs a Rengar Zed and you ping Danger but they ignore you and die shortly after. Most people just shake their heads thinking the ADC isn't listening while others think it's this person is intentionally throwing the game for them. And because they see it as intentional, they think it's okay to flame them cause "I'm just telling the truth, can't be banned for that" as one of these flamers once told me. Obviously they will eventually be punished for it, but they seem to think it's ok.
5) Depends on what you mean by this. Yeah, if someone happens to get first blooded unfortunately, I'll try to help them recover because 1 kill is nothing to come back from. There's no point attacking someone for a few deaths.
However, I had one game where we were red side, our mid lane Ahri just walked straight into the enemy jungle, ran into the enemy team at red buff, got Blitz hooked and died to Draven 1 minute into the game. Draven came to bot lane with Doran's Blade and a Long Sword vs our Kog'Maw Lulu lane. Kog'maw died 3 times in lane due to hooks, and then Ahri was all "bot lane always feeding". That was the only time I really "fought" in chat (I kept saying, "why did you feed Draven first blood" to anything they said against our ADC) because if Draven hadn't have come to lane with 10 extra AD, we might've avoided the first death since Draven got the first kill on Kog and only survived with 50 hp. And the fact that our midlaner was the one complaining made it worse since they fed the first kill to which they said, "First blood doesn't matter."
Most of this goes back to the whole "my team is holding me back" mentality. They'd rather blame their teammates rather than see their mistakes. The fact Ahri didn't get that giving first blood made our lane harder is the same thing, it doesn't matter what she did something to contribute to what was happening, it's the fact that Kog'maw died to Draven was all she saw.
6) Again, depends on how this is approached in my opinion.
Back in Season 5, I was playing and our Leblanc mid was losing to Annie. Our team was raging at her, so I just said, "Abyssal Scepter might help you survive her burst while still helping your damage." I personally don't see an issue with that because some people don't know they can build differently, especially if they are new to the game. Some people know you need to build differently if you are behind. Like if you are a mage against an AD assassin, you normally need to build seekers first regardless if you are behind or not. Or if you are a mage vs another mage, buying Banshee (or the MR component) if you are behind is better than trying to get your Morello complete. However, some people don't get that, so casually mentioning doesn't seem bad to me.
However, I've also had an enemy be all, "REPORT THIS WORTHLESS CAIT, DOES NO DAMAGE." "IDIOT DOESN'T HAVE SHIV/RFC." Caitlyn had IE, Phantom Dancer, Bloodthirster, and Randuins. She said, "Team won't peel so I have to 1v1 the 20/3 Rengar somehow". She had a Riven Top, Yasuo Mid, Lee Sin Jungle, and Nasus Support. Yeah, Shiv and RFC might be the most damage, but if she literally has no peel or defense from Rengar, her item choice isn't bad cause it gives her armor/health/damage reduction to try and survive his attack. In this case, yeah, calling someone worthless for not having the ideal items is wrong on it's own, but that's also the wrong way to point out something about someone's build.
I mean, I once had a game where our Ryze had 2 tears, so I asked, "did you mean to buy 2 tears", which he responded, "wtf....shit" as if he didn't notice. I just asked cause I was curious if this was some new Ryze build or something. I saw a Ryze build Abyssal Mask and thought that was odd at first too, so I asked so I could learn if this was the new OP build or something, not to be rude.
- I think this is more just a frustration thing. You look at your lane and think, "I win this lane", and then suddenly the enemy jungler is camping your lane and all you can see is without him you'd be 10/0 instead of 0/4. So it's easier to attack someone else then say, "ok, I'm bringing this on myself by pushing/not warding/not backing/etc. I need to play safer because the jungler is here all the time."
