wardens got some huge love since uve been gone. enough so that a chap 2 toon i made for storage has become my new primary toon.
wd/s apparently has insane dps with chiron getting beefy and the ability to carry a stat stick bow. wd being melee class u could carry a tiered bow, but i think i would stat a bow with str/stam/patk and not worry too much about using shot.
dont think i would play wd/r. possibly r/wd as anything rogue is currently ...errr..en vogue
wd/w is what i play now. its fun and lvl 40 elite lets u wear plate. being as knights just got turned into weak dps'rs instead of tanks, wd/w is a nice tank build that is a lot more fun then landing holy strikes. ull have to read up on it in these forums, it has been discussed to death so i wont reinvent the wheel here.
so from ur choices i would pick wd/s, rom added the ability to add 3rd class as well so u can add rogue in the mix later if u want. tho a wd/s/d would probably give u great dps toon (s/wd) and a sweet heal toon (d/s)
welcome back, dont forget to take a loan out to buy dias to gear ur new toon
