I'm with OP.
I get that all the required toons have a potential usage, but so does a ton of other toons which might currently be higher on the list to relic. And more or less no toons are worth anything sub-relic anyway.
It is worthwhile having BAM unlocked however, for his ship, for being closer to rushing him (and potentially the rest of his team) should they become required, to use him in a coming heroes journey/similar for new toons, to up him and use in a pure Mando squad or simply to deal with any new feats from CG pushing BAM ownership.
Probably not any of the latter coming at this point, but better safe than sorry...
