Why is preseason always unplayable for 2 months?

If by broken you mean functionally broken, or overpowered there is a difference.

Thats not even the problem. The problem is the game is focused on dragons, everyone does 1 shot damage, supports are useless and more unfun than ever, rift can be grabbed twice and towers are still made of tissue paper, items are just beyond broken. Minion block is still a thing, button presses randomly dont register on 50+ ping. Random inputs happen and cause you to use abilities without pressing anything on 50+ ping. Client still crashes and bugs, CONSTANTLY. Minion block is STILL happening and is getting worse every season. Alcoves are useless. New dragons map changes are so stupid its unreal. Dragon soul is broken, mountain drake is broken. Minion block is broken. Fix the game riot you have a pbe for a reason instead of just using the live version as a testing ground maybe use the TESTING GROUND you ALREADY have?

game has always been focused on drakes, at least now it makes sense for it to be so as the mechanics accommodate the approach. very few champions do one shot damage, the ones that do outright have to or they lose. supports are the same frankly, you're either good at it or you aren't and that dictates your entire outlook on the role, you should try playing some janna. rift being gettable twice is negligible, literally do not care about it. the only "broken" items are mage items, once again. minion block was a conscious design choice made in season 1... i play on 200 ping and my button presses register just fine. there are no random inputs that's just you clicking something you didn't want to be it an ability icon or the minimap. client has always crashed dating back to "le golden years," that aside current client is very pc friendly as far as i'm concerned, i can now leave the client open for a week and it won't start hiccuping my machine when i attempt to make it do the thing it does after 4 days of being permaopened. minion block doesn't get worse by accident, that's riot nerfing player mechanics because people are getting too good for the scope of the design. alcoves are brilliant additions, use your brain instead of saying they're useless. map changes are good, finally something to make these lazy brains playing league actually think about the changing state of the game. dragon soul is supposed to be broken. the rest you repeat as though it'll make your argument valid.

also the pbe cannot make any competitive balance checks, it's not a competitive server. i mean come on man, all that server is for is bug testing obvious bugs not for balancing things to perfection, and really it's working as intended, like most things introduced this patch.
