This is why I respec all PVP AP points from SMN/SCH dual spec to BLM whenever I wind up in a slaughter match. Summoners are great at lowering the health of a crowd but no good kill shot procs, the best you can hope for is to get all your DOT's on a target while they're in range and use Fester without another class using a skill that procs off low HP getting it first. I only have something like 250ish kills on the achievement board so far since it started getting tracked.
