Set up the start of most fights with nocking two arrows with Multi-Shot, followed by a Ferocity II & Raging Strike II buff, (Hawk's Eye thrown in depending on whether or not I'm initiating the mob), followed up with a Trifurcate and the use of Heavy Shot to build TP to 2500, then throwing out a Bloodletter, then Foeseeker, followed by a Raging Strike II (CD should be down) & releasing Trifurcate and following up with Feint for good measure as I've found once the battle is initiated, more often than not at least one arrow misses.

Generally on basic stuff like Behest, leves, etc. I generally just spam light shot and throw out Bloodletters or Foeseekers with appropriate abilities thrown in. If however it's a longer fight a la the NMs, I'll start off with the above.

Gear-wise, well... to be completely honest, there really isn't much that gear actually helps out yet in the game. Stats are far too wonky to prove any real importance, so as of right now despite having what seems to be the norm for gear for ARC, it's all aesthetics for the time being. But I rock Harrier's Jacket, Skull Eye Patch, Spiked Armguards, those crappy rank 39 toadskin boots, tarred leather pants, tarred voyager's belt, silver ringx2, str+5 ringx2, -BOTH- a Crab Bow and a Yew Long Bow and Warped Arrows. Not bothering with any other form of arrow at this point in the game, as it simply just isn't worth it at this point.

That's my ARC in a nutshell, seems to work fine for the time being but until they revamp all their planned changes (classes, battle systems, stats, emnity generation, etc.) I'm really not too concerned about whether or not I'm an optimal ARC.
