Is it possible to get some dev clarification on this? I've poked around these forums and on reddit, and I can't find a clear answer. People are saying at least three different scenarios happen when you fight the squad again (in GW or TW):
A) The original leader's ability still applies.
The toon in the second slot becomes the new leader, and if they have a leader ability, it now applies.
C) The squad now has no leader ability at all.
I think that B is the case, but lots of people confidently assert C, and some still say A. Does anyone actually know for sure?
