Huh. I like the idea of giving homebrewed abilities to the ranger at different stages in his combatstyle progression. Before we give either class more abilities, though, it's important that we playtest the existing ones. I've put a link to the new arena in the OP. The revamped Ranger and Monk as well as the PHB Fighter and Rogue are needed to test their usefulness and balance alongside benders in combat.

Playtesting Arena: Round II

While we're waiting to get results, though, I'm completely stumped on feats for one-handed melee and two-handed melee combatstyles for the Ranger. In the old thread, it was suggested that the styles be broken up into more specific strategies (sundering, multi-cleaving styles, etc.). What do you guys think?
