I agree and disagree with alot of the balancing. Overall I think it's a decent start to finally getting rid of burst meta.
Caut/Wrecker and healing output have been ridiculous since forever. Healing early game is incredibly frustrating to play against with nearly all healers able to out heal any amount of damage from a single champion, but then late game healing practically doesnt exist, similar situation with shields/wrecker. This balancing brings the numbers in line so it's less op at start and more useful at end game.
Strix, all his nerfs were needed to stop him being able to burst anyone thats not a tank at ANY range. He's been OP forever, it's about time. I say he needs more speed bonus in his stealth or something else buffed to counter balance because he looks a little too weak now.
Although they've created new balance issues and left out alot of old ones, I think most are surface level that can be easily tweaked as they go along. But most serious issues were deep rooted in the Caut/wrecker/heal problem which I'm so glad is finally being addressed.
