To be fair, it's almost impossible to bug board things like devils betraying...After all they form their opinion on you over the course of 30-45 minutes average IRL time.

It's just something you get a feel for. Given the scope of the changes - there's no way a normal person would guess the new magic formula given how long the old one was in place for.

I'd be ok with devils getting marginally more defensive and reliable at the cost of being significantly less lethal (no rot, significant damage decrease on their casted spells..ie, no more ANNI/ERAD spells hitting entire groups).

I don't have a standpoint on whether or not they're OP/Underpowered right now - I haven't played one - but as someone who pretty much never used devils to begin with I still felt evil conjies were very strong before - just not if you plan on playing the "no wands" route.

And for what it's worth, I think archons should be "angrier at doing nothing" as well. I never had an archon turn - ever - no matter how much I was just 'idling'. I'd love to see some downside to hanging out in the Inn with a pocket healer.
