you can still use the guide for s/w for s/wd. The melee weapon will change to 1-h sword, and the rotation to: snipe, vamp, combo shot, shot, shot, shot, combo, shot, shot, shot, hidden peril, if that gets the buff=snipe--otherwise start over at vamp and mix in hidden peril when its cd is ready to try and get the 1 sec snipe.
*always keep entling offering active to get double hits from shot.*
The only skills that you should use that use mana are the savage power(a burst phase buff), the briar shield(15 min def buff), entling offering(15 min double shot), and elven amulet(oh crap, run away). So the main "fuel" to be concerned with is focus.
You can use the charged chop, which does 3/4 what snipe does, but it is still currently on a 2 sec cast with 7 sec cd. The 2 sec cast rate is a bit long for most players taste.
