I think i was picturing them less as ranger types, but that works well too.
Searing Strike: their not there level... it confused me when i read it as there
Unwanted Victim: the wording is off, plus I could easily see Undead being drawn to these guys rather than be averted from them. Essentially because they can hurt them more than most. I'd just give the benefits that they can never be turned into undead and maybe something else.
looks pretty good
