Some quick notes on Genji and Reinhardt in Stadium:
Reinhardt’s ultimate charges way too fast, and his fire strike is ridiculously strong—it one-shot me at 315 HP. His melee attack also hits far too hard for such a tight map. If your tank picks Zarya, you’re stuck with a huge disadvantage since role switching isn’t allowed mid-game, so you’re basically doomed.
Genji’s mobility is excessive for small maps like this. His third-person perspective makes it way easier to play him. On top of that, his ultimate feels way too strong when compared to most other heroes in the current pool.
These two characters heavily counter the majority of the roster available in Stadium right now. I’m pretty sure that by next weekend, once everyone catches on, nearly every game will revolve around a Genji/Rein comp.
