I'm curently hesitating between two skills : Block Master and Battle Rage
The way I see, in my early tank level I will only be able to have one of those skills. Can't decide which one, both sounds appealing.

The first can grant as much as 40 energy a block which is really not that bad : power attack, block a few hits, then power attack again. Nice, plus you may sprint with the bonus stamina which can be handy for pursuing/escaping.

The second looks good to, If I understand it right that is, +50% phy str (I believe/hope they're refering to mastery ?). Well not much to add a part from the fact that it consumes 10 CP. I believe that may be a problem as a Tank since I'll spend most of time behind my shield therefore I'll have a meagre CP generation. And that CP may have a better use (crowd control).
In the other hand it could be really handy in 1v1 situation or when you need to punish someone fast.

Looking for your advice, thanks for reading.

Depends on your playing style. If you like to block, then power attack, and not normal attack frequently, get your block master.

If you like to duke it out, and wish to dish out more damage to bring down your foes quicker, choose battle rage.

When you reach 10+ lvl, you shouldn't use Battle Rage, because there is more usefull skills

That's what I was thinking, thanks for the answers.
