Boards are divided between assassins.mages and juggernauts.
One of these 3 groups are always complaining about something.
Mainly that's it's unfair that their main (champion, not the class) is nonviable and it's unfair because the marksman class as a whole always has at least 2 good champs.
And there is a huge amount of Darius mains that want him tankier than cho gath with more damage than Fiora.
Also impossible to kite, and more resistant to harass.
Juggernaut mains who are finding their champs unreasonably squishy following the changes (probably justified in some cases)
Assassin mains that want to be able to kill 3 people all at once,under a second with no warning, or at least somehow get past all those pesky lulu´s (the last one i can actually understand)
oh they also want to 1v5, or at least 3v5.
Mages want more items,fun items, situational items and more AP, also some way to deal some manner of damage to tanks.
Explosions and implosions are also high up on the wishlist, along with mana potions.
Marksmen mains are far and few between on the boards, supports do exist but they are a diverse bunch.
I myself? I play all the roles to some degree.
My top 3 are as follows, 1 mage, 1 diver, 1 marksman.
Then.....i think number 4 is a support?
Jack of the trades^^
