I agree legions mastery was just meh for survival, but it’s better than what we have now which is both bland and weak. That’s why I said fine, whatever, because it needed to be improved, but instead we got a mastery they felt wasn’t good enough for a spec making good use of it to improve theirs and then nerfed it to give it to survival, which didn’t even see the level of effect from it that marksman did.
Survival definitely needs modifications, either tuning or a change, to the mastery a top their other needs - an active developer for starters.
