Weekly hero pools makes a lot of sense on the competitive ladder to avoid player-to-player griefing, but it's ridiculous that this is coming to the league. Meta compositions and heroes play a gigantic role in how individual teams perform, this is not a well-kept secret, and now that we're already varying play with conferences, travel and scheduling, Blizzard wants to crowbar in an RNG meta-maker each weekend? Instead of just instituting hero bans like we asked for? Whatever. At least it's in character with their other authoritarian tendencies of late.
Also, am I the only one who doesn't want Blizzard to balance the game with a sledgehammer every week? I just want fewer stuns, shields, and abilities with cooldowns longer than 12 seconds. You don't have to delay doom's uppercut recovery or make mccree a bit thicc to make it enjoyable.
