Dear Small Giant team,
As a former retired game designer, have a gameplay idea to enhance the game.
I think alliance wars are fantastic - keeps old time players engaged in the game longer, being able to use more than 1 team for winning.
Imagine a game mode called: tag-team battle.
By default there would be 2 rows of defenders (and attackers) set. This means we create row 1 which starts the battle. Once row 1 tank dies, row 2 tank appears. Once row 1 right wing dies, row 2 right wing takes its place. So while you can create rainbow teams, battles could be fought on while all opponents are dead. Strategies to create different colored rows or diffenetly placed rainbow teams could play important roles as well as similar setup than clan wars where you have flags to spend on teams.
If time allows even 3 rows could be defined.
Rules could be even after 2 minutes to switch rows if players exist (fresh players come to play on both sides) or random effects that influence gameplay (like row 1 can be 5 stars only, row 2 can be 4 star troops or the other way around).
I think this could be fun and likely doable. What do you think?
