What I currently find frustrating about League

First before we all say that this is me whining, please re-read the title "What_** I **_ currently find frustrating about League".

Alright then.

This is the TL:DR before I explain it for everyone, because I know most people don't read a long explanation before the TL:DR, So here you go :D

Zed (Not AD Assassins) is way too strong.

ZZrot and Banner of Command, allow a team comp that is based around team fighting to split push better then ever.

Too many champions are going over the radar without anything being done about them, and simply too many people to ban to ban them all.

Games are simply ending too quickly.

Roles, just do not feel the same as they did in the past.

Champions that are needing help are not getting it, but other champions that do not need help are getting too much.

So lets begin this long explanation.

Zed, is currently the safest Assassin pick in the meta. Due to the fact that he can farm like a mage, kill like an assassin. There is no repercussion for him losing lane, because he can farm under his tower just as well as any mage can. This is due to his passive, and how his skills work. But if he isn't losing lane, then he can just go under your tower(s) and kill you, if you let yourself get under 75% hp (I play squishy champions mid and like to bring ignite)

ZZrot portal and Banner of Command are simply too strong for lower level play (I just witnessed my team ignore the zzrot portals and promoted minions). I just watched my team let an enemy top laner, and support build both of those items and take the whole top and bot lane with them, because they were all busy teamfighting. If the enemy team picks champions made for teamfighting/tanking. They can shove a lane really well, while forcing teamfights in another lane, even if they lose the team fight they still won the war because they got a different tower/inhib.

Simply put, right now. The constant bans across the board seem to be. and more. Simply banning 6 of these guys means 2 are left open. But if your person that WOULD play that champions doesn't play them, then its free for the other team.

Games are ending too quickly. There is no space for messing up. The second that one team messes up or player messes up, that generally will cost a tower. Such as leaving lane to back and buy has costed me mid outer tower many times, because the enemy jungler just happens to walk by and notice I am not there, at 8 minutes in game. First tower is gone, or Vice-Versa, I force my enemy laner out of lane, 2/3 of his turrets hp is gone before he can even get back in lane. Turrets do not offer any sort of protection anymore like they used to, they are paper towers that crumble the second you wiggle them. Also roaming has become so rampant in the game, that by 11 minutes in my games, I generally have 3-4 enemies shoving down mid lane, as I take the harass and clear the wave to try to protect my tower from going down.

Roles not feeling the same. This one is hard to really explain as much as how it feels to me. The Basics of every role is still the same, but when playing them, they do not feel the same whatsoever.
How I used to feel about ADC in the past season: had to know how to position so that they didn't get nuked and instantly die. But today, ADC can get Steraks, and Itemize accordingly for whatever burst them down. Hexdrinker, QSS, Steraks. They don't have to be as good about positioning as they used to be. Mids with the lack of items for armor, feel like the new ADC where they have to be in constant fear of where they are and who they are around. We can build our tanky/ defensive items, but they are not simply strong enough for us when we have cooldowns that are 2-16 seconds long, vs other AD casters who has 1-3 second long cooldowns. Support has become much more aggressive or defensive, because you either know you are going to lose the bot lane or win it. With how the game currently is, neither side wants to lose because thats a huge difference. (Don't play much support, but I feel as though supports are much more aggressive when it comes to ganking mid etc. Someone that does please tell me if you sense that or not.)

Jungle is actually about the same, the champions change though.

Top lane I can not say at all, I refuse to play this lane. Just the whole lane annoys me. Because I refuse to play it, I am bad at that lane.

All I have to say about whats going on with champions right now is vs how needs changes.
