You should have the options to choose different amounts of lives for each teammate in survival matches... that way you could do something like a team of 3 units with 1 life each against a team of 1 unit with 3 lives
Squealed with delight when i saw a sequel. Awesome game! I dabble in game design myself, and I've always wanted to make a medieval tournament style like this :) 5 out of 5! Suggestion- Perhaps let Unique heroes not bought by the player be bought by other teams, and have the option of trading with them.
Old but funny bug. Will be fixed in 1.44.
