The amount of stuns/cc/etc in this game is horrendous.
Stuns are fine but when they last 3-4 seconds it ridiculous and reduces the skill it take to actually play a champion. For example, Annie doesnt need a stun that long or if you think she does make it burn away other she can hold it forever. The reason i say she doesnt need it is because at lvl 1 with stater items she can burn you down in 1 combo to 1/4 health which is ridiculous. You may be like well counter pick a champ that is ranged. Well considering there are 120+ champion the majority of your players are not professionals and dont have the time to put in to learn all of the champions or even just the amount for one lane.
But this isnt about just champion stuns, its also about items. You got items that cc. So basically you can render an opponent unable to fight back, while that maybe be awesome in real world military situations it doesnt do anything for a game that should be skill based, not who has more stuns.
Feel free to complain and get butt hurt over my post while i figure out a different MOBA to play.
Note - Stuns may not actually last that long but it feels like it.
