I don't disagree... I didn't like the ward wars. I always liked support because I could focus more on the opposing team than last hitting minions (one of the stupidest mechanics around IMO).
But supports are useless now. AP supports do no dmg, even the heavy harassers like Zyra, Vel, or Brand might do a bit of dmg in lane, but lifesteal and runes now mean a single wave and any carry can top themselves up no problem. Tank supports are limited pretty much to Ali now, anyone else (Naut, Tahm, etc...) are so stupid squishy they evaporate instantly. Sure pyke is around but he's just stupid OP. Blitz is weaksauce now, landing a grip now means instadeath for you, not the opponent; his wombo combo is now a tickle combo. Healing supports can't stand up to the burst. Soraka is a joke, sona went from OP pretty much S1-S4 (when I stopped playing till recently) to a free kill (I saw her once the entire two weeks I reinstalled).
But what was by far the most disheartening was that no matter how well I played, my contributions didn't have any tangible effect on the game outcome. Time after time we'd own bottom lane, be 2-3 kills up, and top or mid would feed an assasin 2-3 kills, and then Yasuo, or Yi, or Zed, or Akali, or Talon would then start running around just deleteing people and that was it. It didn't matter how many skill shots I landed, how much CC I provided, there was no counter to a fed assassin/hypercarry. And where-as previously (S1-S4) you had to get around 5+ kills ahead to be 'fed', now 2-3 was sufficient. 1 bad jungle gank and it was game over 6min in, no matter how well I played.
They could remove support from the game, just make Summoners Rift 4v4, and no one would notice a difference. They bring nothing unique, interesting, or useful to the game anymore.
