Simple Overhaul for Team-ups

Sandmaker

Here's my suggestion for how to overhaul team-ups:

-Remove team-ups as random drops and items.
-Team-ups are selected from your roster. Same level, same strength as the character you chose the ability from. Cannot be someone on your current team.
-At the end of the round, characters chosen as team-ups take damage equal to the average of the health lost in your team.
-On defense, team-ups now reflect what you last used in battle.
-Keep it as an alternative to boosts. Players that full boost on offense, gives up team-ups on defense.

Essentially teams-ups will now function as additional partial character slots.

These changes will benefit several things:
-Add a new layer of strategy for how you build your offensive/defensive teams.
-Makes team-ups consistently available to players
-Reward players on defense for not using boosts.
-Sell additional health packs.
-Give purpose to a more diverse roster
