I presume that because you posted in the warrior forum, you want to know which warrior template is best for supporting both yourself and other templates. (I say this because my support characters are mostly mages)
In that light, you could adjust your sampire to Lynk's template (all of the above + healing. You need significant skill gain jewels to accomplish it). I can't find the exact details, but I'm sure you get the point.
Or you could go with the ABC archer, which lets you heal the person under attack while avoiding attack yourself. Or you could go with straight samurai (healing instead of necromancy on your template) and you'll be very good under attack as well as attacking.
Or if you had faster casting and a good mana leech weapon, you could cross heal with chivalry. I found it quite inconvenient when I worked that way, but it is possible and very helpful if someone else is in more trouble than he can handle.
The +chivalry item is also a good piece of advice. I used to carry around a Luna lance (uninsured, I have a ton of them) just in case people needed to be ressed.
