It should tick 6 times not 5, and as I showed earlier that 60k healing makes it more effective than a rampart when used effectively, which part of that maths dont you get Im happy to explain again. It objectively does provide survivability in a group pull so im not sure where youre getting that from.
Edit: looking at camos numbers and aurora, to have a "beefier camo" in exchange for aurora youd have to buff the shit out of camo (like buffing it to 20% still probably wouldnt hack it due to the uptime difference) at which point youre creating a situation where gnb could have more cooldown power than it necessarily deserves when it comes to dealing with TB's.
@hierro:
In conjunction with my healers, and by planning out auroa uses i can go pretty much the whole section I tank in e12s without receiving a gcd other than maybe a regen from my healers. Also again, im not sure if you saw that quick calculation I showed earlier, but healing 27% of your HP is actually more mitigation than a rampart will give you most of the time, and its on a lower cooldown, can you dispute that, id love to see your reasoning.
