As a 218 Opi Doc, ther aer some ups and downs...
For stam, yes that is a topic of concern becuase (for ex) our LE armor is Stam based >.< (Curse you FC) BUT.. there are many stam buffing items ingame over the rest.. if you are concerned with high lvl items, then one benifit as a doc is the Star of Recovery (SL) wich adds 60, for mid level, there is the Doc Pill Pack (20 iirc). If you go pistols you can gain another 50 (2x G2 pistols, or is if 40? at work so can't verify).. I can easily get 1100 Stam with help and perks... (of course soli would be able to do it soner)... I don't much prefer PvP hence my lack of Ofab gear (though I only care about back and helmet.. 60k VPs YIKKKKES)
Things that are effected... that we docs love and need:
HP (STAM)
MM (multi Mellee for you mellee toons) STAM based (str too?)
MR (Multi Ranged for us pistol wearers) AGI Based (and I think sense? really wish I was at home to check)
BUT!!! as Opi, it is easier to get SUPPLE on (If you have AI) and the trickle from AGI really helps when you nned the MR (I just put BOTH my doc pistols on this past weekend with only 3x pieces of supple and NO pande loot the MR is the kicker :/
I have had a blast with my doc atm.
Ranged or Mellee? well there are MBC/SHEN/Pistol/Dread panther (good job by the way )/ and various other wpns... I would say the doc has the better variety of wpns to wear (or attempt to wear) because we are masters of none but can hold our own with most.
Shadowbreed... don't based your dicision on SB!!!!! if you are thinking of soli for the perception... forget it.... you can find some one to pop it, if you need to get the scope on... but you will see there are many things that also are great in that hud3 spot as well that fight for contention (1k HP attunement device is my pref with a 5 hr recharge... you actually forget to ever use it... except during raids/PvP for any proff. I have used my 3 times (once just for show) in the past 8 months...
Sorry so long but Bottom line: (If you have played a while) Go with how you like to play, or envision playing your doc. (If new) You can't go wrong, both are solid, as there are many ways to compensate for the differences.
Just my 2 cents worth... Your Mileage May Vary (YMMV)
