My biggest issue with zenless so far is that not having a second a rank stun character makes early game team building incredibly restrictive for some accounts
This problem will go away with time but I think the 1.0 launch roster, while all plenty charming in their own right, is incredibly poorly planned and might have long-term (or at least medium term) ramifications on player retention
How are you going to design a combat system around stuns and burst windows and give your players easy access to just a single stun character?
