Give preseason some time before coming to conclusions
So as I'm about to head to bed I thought I'd add in my thoughts on the preseason and everyone's reactions to it so far. ADC's can fee stronger or weaker and in some cases may very well be clear that they are (graves, kog maw) Certain items may be op, may not be. I remember when devourer came out everyone was calling for it to be "op" and everyone banned shyvana, kayle, etc. Well, for melee champs that item is mostly the same and those "broken" champs are not played nearly as much. My point is everyone eventually adjusted to each meta. In each meta there has usually been a few truly broken points. In the tank Meta it was Sejuani and probably Sion. In the assassin meta, Zed was out of control. In the ADC meta so far it clears Graves is overpowered. But for the most part, people adjusted to the meta games and realized certain things were not overpowered. Master Yi, Shyvana, Xin Zhao with devourer were all "too strong" to certain people and now people don't even consider banning them. The juggernaut patch gave way to Darius, Garen, Mordekaiser, and Skarner. After one of them got hotfixed, people whined and whined that Darius and Garen were op, but now both are realized to be very beatable, even in competitive play darius was played less and less as world's went on. People learn how to adjust to something new.
My point? Give this preseason some chance before you freak out and say its all bad. There are certain aspects you will certainly dislike and I even my own that I hate. But give it some time, try to adjust at the very least. You'd be surprised at how the game will feel in the end. Your cries of broken this broken that or shitty change this may very well be true. But you could gasp be wrong as well. Just try to learn how to play against these new changes and with them. Riot has a plan for the game and I'm sure they didnt put these live without least testing them internally for general feel. If the game gets stale or un fun because of changes I am confident they will find a way to fix it. We will probably never have season 5 again so get over it. Just like you got over season 4. and season 3. and so on. I mean there was a time altogether when trinkets werent a thing. there was a time deathfire grasp was a thing. I mean, we ALL adjusted to those changes and it turned out fine.
League is still fun, its just adjusting to changes is NEVER fun, just give it a chance. try to learn new strategies rather than complain that your old ones aren't working anymore.
