Champions With easy difficulties.
I have no problem with them being in the game, as every game with a high skill cap needs some easy things to get you going. But as I've noticed, champions with higher difficulty ratings in-game like Syndra or Katarina, are very powerful, but only if they have a lot of items, while champions like Zyra can one-shot you with 2 doran's rings and a blasting wand. It seems to me like if you just go full-tank, full AP/AD on harder champs, they will fail most of the time, but on champs with lower skill they are really powerful. What I'm saying here is that champs with low skill levels can do well late game with only about 2-4 completed items, but if a champs has a skill level of about 7 or above, then they will need like 4-6 items to do well. Now I admit that if a hard champ is played near to perfection, they will be as strong as a easy champ, but that really doesn't matter most of the time. Here is an example: A while ago, Faker did a 1v1 zed vs. zed when he was at 1/3 life, and won because he was able to dodge all the skillshots. But if he was up against a draven, the draven would just click on him and kill him because he was at low life.
