Why does this game offer virtually no chance of making a comeback?

I'm just going to start off by saying that OF COURSE YOU CAN MAKE A COMEBACK. But the thing with that is it's dependent on other lanes doing better than yours or getting that one player who can carry your team.

What I'm referring to and this is especially true for the bot lane, is that you die once and it's 300-400 gold to the laner depending on if it was first blood. and 600-1000 gold to the bot lane depending on if it was a failed gank and or if it was first blood.

So let's shorten this a little bit. You're mid lane and your mid laner is who starts he kills you and gets a few cs with that kill and backs because chances are he almost died from a duel. So he's back at base and comes back with . You're still stuck with or or (for the champs that use a lot of mana). Now at that point it feels like there's no coming back unless you get a gank from your jungler which sadly I find rarely happens now.

Ok now let's go bot lane. the situation is that you and your support die to the enemy adc who then gets 600+ gold and comes back with while you're still stuck at or . Now it feels like there's no coming back because now the enemy ADC and support no longer feel the need to play passively.

Ok Now top lane. Your laner comes back with and the same thing. You feel overwhelmed and your lane is the easiest for a jungler to gank so now you just want to play passive under tower losing cs and your laner is always ahead.

On top of all this you're getting harassed by your teammates for doing bad so you have to mute. Your jungler has already decided to join in on the harassment and decides that you're not worth ganking so your lane is now getting pushed in to tower. In about 10-15 minutes game time you lose first tower to the top laner. Now your top laner decides to either roam or keep pushing and since you don't have a tower, the enemy jungler can now gank you with little risk at this point.

All this wouldn't feel like such a burden if I didn't get harassed by my teammates. Who somehow think that a losing a lane=inting?

Ok now I decided to go play aram because the rift isn't working out for me. I've had 5+ game losses and maybe aram will set me right, right? Nope the enemy team has all poke champs like and your team is something like this .

Maybe I'm just looking at this from a negative point of view, but this game just seems to get more un-fun the older this game gets and the community is already subconsciously trained to think that everything you say is negative. It's like you go 2/6 and someone on your team is playing a champ you know very well how to play and what to build. So that person build something odd and you go"hey nasus why are you building static shiv?" And then he says something stupid like "2/6" as a way of somehow justifying himself? and thinking that mentioning score is a winning discussion?
