Tanking advice as a Marauder/Warrior

[Nabian]

I do see the problem with flash not worth it. i was refering to lower level im afraid. at lower levels its a good policy to have it, for me at least, due to the sheer fact that everything eats tp and i use it as a 'breather' move.

Also i would like to ask something. Mantra. is the 5% really worth it? it gets convalence to 25% since it stacks, but is it used for external healing or do our bloodbath/second wind kicks it as well?

It's very situational but unfortunately you don't have many better options. For example think about Leviathan's 2hr move. Popping Mantra in the absence of a Monk provides an extra 5% healing to the group. No it's not required...but I still find it more useful than flash.
