1k health over time is going to be more EH than last stand given a 3 minute fight. The question is whether or not it's worth the burst. Now, that's tougher given something like health, which is more TTL based, so we'll go with something more similar: would you trade shield wall for 8k armor?
Given the option to prioritize between one or the other, which do you think would be more valuable in learning a fight?
I've always thought that cooldowns have been crucial to fights, and armor has been good but not great (especially given how much non-armor related damage is out there). But again, different perspective I suppose.
