I'm going to pivot a bit from Aetherbard's question - in the upcoming errata, would you be able to remove Challenge tokens with Put It Out (either on yourself or an ally)? It feels like turning Challenge from a turn of tanking into a one-action tax is stronger than intended, since Challenge tokens can't stack in any way - an action tax is very strong, but still totally different mechanically from what an Angel, Reversal, or Zen stance might want - but at the same time, even in the current version Put It Out would be able to calm an ally down from a Challenge token.
