Slam is (afaik) the best daily power we have, it ticks away the damage written on the tooltip (each tick is for the tooltip's damage) and it allows you to continue and dish your normal damage. I haven't counted the ticks yet, but there are enough :)
This class is a lot of fun, and while from a quick glance at the Rogue (level 5 or so) it seems like they'll fare better overall, the GWF has one of the best 2h Warrior styles I've seen in any MMO, by FAR! As for advice and tips: 1. Focus on AoE but make sure you still have at least 1 good attack for single targets since…
