I think gold toughness is fine. I think being able to spent 90% of a mission with gold toughness up is not. Being able to reactively protect yourself/the team from a Sniper shot, or a Crusher overhead, or a Poxburster explosion with a well timed shout is a cool gameplay feature… if it actually required timing and resource management, which it currently doesn’t.
I think you could do 2 things to fix the problem. The first is obvioulsy to giga-nerf Tactial Awareness, probably by giving it the Invocation of Death treatment (seriously, all CDR talents should be like current Invocation). The second would be to maybe make it so that you can’t replenish gold toughness through normal toughness regen methods - it lasts until enemies break it or the duration runs out, no keeping it topped off with Confirmed Kill or whatever.
Duty and Honor should also probably receive the cooldown penalty that the revive-shout talent currently has - Fatshark really missed the mark when evaluating the relative value of those two talents.
