Daily enemies hit way too hard.
Hitmonkey can 1shot R5 5*. Granted that's with a whole 1 medium, with might charge, but what is wrong with your team that these daily enemies are hitting loose tanks? Stealth spider killed a R5 in 5 hits. That's one combo.
You've already heard that people HATE your design when we have to play 0 hits taken, and you idiots brought it back? This is a bug and no one was so stupid as to make it on purpose right?
