Capital Games TeamCG, regarding undersized teams, I'm here to bring you a solution that suits both you and the community. A good solution would be to change the Execution stacks at LV based on the number of characters, at least at high relic levels (R8 and R9). Currently, they're 25 with a full team and 15 with a reduced team (whether it's 1, 2, 3, or 4 characters).
If they put something like this:
*10 Stacks = 2 characters.
*15 Stacks = 3 characters.
*20 Stacks = 4 characters.
*25 Stacks = Full Team.
They'll probably eliminate 2 characters teams, and you could still do 3 or 4 characters. Another solution would be to force you to use a leader at R9, which would eliminate the team of only 3 clones. It would be an "understandable" nerf. Now, if they use much more than that in small teams, they'll ruin the Assault.
