The most powerful rogue powers from Martial Power.

[Ibixat]

Personally I really liked strong arm enforcer: I've found that my rogue has problems defensively speaking (he tends to burn through surges quickly, but in return causes massive amounts of damage), so a PP that
1) increases the penalty for a marked target to hit me
2) allows me to mark targets
3) gives me temporary hitpoints

is bloody fantastic. Previously I was "meh, I guess I would take daggermaster: it doesn't seem too bad". Now I'm excited to be looking forward to strong arm enforcer.

I also quite liked the rattling attacks.

The other rogue PPs are pretty nice (except I hate the racial specific ones: of all classes), and if my character was a bit different, I'd definately consider taking them.

Rattling is one hell of a keyword actually, it's very powerful, I'm actually kind of suprised that it's so good and on as many powers as it is. I will be going daggermaster for the 15% crit and the free attack off the crossbow when I do crit as a two fisted shooter drow rogue, I'll be taking the drow fighting style and upping the crossbow to d8's, if I were another race or had the ability to get a 19-20 crit range feat due to my stats I'd definately consider that PP.
