Problem is both thief and mesmer can regain their profession mechanic “resources” without much interaction with opponent (initiative regens and there are numerous ways to speed up / gain it, clones are attached to skills and dodge if traited which restores you back to 100% in seconds). It’s not so easy for necro, without things to kill or use high-LF gain skills like ghastly claws or spectral grasp you are screwed. Would be nice to have some skill that would give ~30% LF out of thin air (without killing target) on medium cooldown, could be attached to some of elites, lich for for example
