R/me = pvp, for the sake of mantra, this prevents you from interupted from laying traps, at the expense of energy each time. not bad, however, you're a ranger, and whirling defense is nearly as good. Very often, i offensive trap with 2 people swinging at me, and whirling defense is ussually enough to get 2/3 or even 3/3 traps down, and with high wilderness survival, it's nearly 20 seconds long. furthermore this protects you from damage as well, so it's multi purposed
my current offensive trap setup as a
R/Mo
healing breeze, troll unguent, spike trap, dust trap, flame trap, storm chaser, whirling defense, res sig
i can heal my party up a bit, or at least slow down degen. i can heal the hell out of myself with troll/breeze, and i can trap like crazy. of course i use a staff with this setup for the extra energy, and a full druids set. 42 energy goes a long way with 13 or 14 expertise.
in pve, i switch out the sig for rebirth or restore life, rangers don't die a lot, so with storm chaser/rebirth i can ussually recover a wipe, even if you're dead at their feet.
judges insight gives a lot of damage potential in a pure marks build
there's a smiting aoe that hurts enemies around you, with the current ai, you can ussually get a dust trap layed down before they come back, and then lay the other 2 cuz they're blind.
a lot of options with
R/Mo, i ussually run 5 or 6 ranger skills, and 2 or 3 monk skills, and i find i get a lot out of those 2 skills.
another option is to go
R/W, making you a great runner, and with greater conflagulation (elite) and drakescale armor you can outtank most warriors. combined with the various ranger survival skills, and cheap warrior skills through expertise, it's a very fun combo.
my 12 cents, hope it helps
