I can't say I find the prospect of a Haste, Refresh, Phalanx, Regen, Reraise, Spikes, Gain, Barelement, Barstatus, Aquaveil, Blink, and Stoneskin cycle appealing without vastly significant duration boosts. I'm talking like a half hour for everything that isn't consumed in some way like Stoneskin or Blink. And this doesn't even account for new stuff that may come about if pimping the defensive angle of enfeebling. Regardless, you'll get no argument from me about converting merit spells to scroll learned.

Otherwise, while defensive enfeebles can justify some higher potencies since they'd inherently carry the risk of taking damage or some other condition, offensive actions will ultimately see more immediate results that people will hone in on in a game where a strong offense is often the best defense. It's not so much that our enfeebles are useless on fodder, but more that we can't inflict them all in time to be meaningful. To that end, I wouldn't mind more combined spells that don't sacrifice potency for the speed of infliction, perhaps leading to a Bad Breath equivalent for RDMs that doesn't suck. It's just a matter of deciding how to pair/group effects, like how Radiant Breath inflicts Slow and Silence on top of its damage. Actually, it'd be nice if whatever new enfeebles carried a slight damage component, or sin of sins, TP generation for the RDM.
