I hear your points.
All I'm saying is that there is more than one way to make things more challenging, and in an 8 player team with 6+ barriers, there are a lot of ATs that don't have a spot other than as a charity pick.
On the other hand, if you had a small group with an encounter that specifically required other Destiny Slot abilities (Incandescence or Clarion for example) then maybe, just maybe, we could shift the meta to include a few other ATs.
Or to put it another way, bigger defence and tohit numbers aren't the only way to make things interesting.
