The commando merc adrenaline ability will take them to 75% or at least 65% health whereas our own only takes us to 35%. I honestly feel like vanguard/pt is a pretty sub-par tank in comparison to Guard/Jugg who have saber reflect, 40% damage reduction increase and that 25% shield along with the 12 stacks of hp on damage and their 40% hp boost.
And what exactly is the point of trans-locate, it's rarely needed and you also juggle whether or not the other person might say "hey ***, why'd you do that"?
