Every patch there are bullshit S tier heroes, I don’t even hate this patch but it’s just been going for too long. Imo though Antimage, Spectre and Tinker make for the most stressful Dota games if they’re over buffed. Tinker especially getting perma hexed and him spamming pewpewpew as you get lasered to death
The worst metas are the ones where the strong heroes can completely 1v9 dominate a game if the player is a smurf. Tinker, Arc Warden, Meepo, anything that can split push hard while also killing everyone without there being anything you can do, against them you can’t win through teamfighting and you can’t win through splitpushing.
