The change to "Slowed" made WHEYTWUT a bit more powerfull (but it was ok allready). I've been using it at the early stages of the game and what really made it work for me was the realization it actually overlapped with GETINDARE.
Funny story (that I allready told) same thing happened to me a bunch of times. Ever since I ran into Soul Orb, i have this strange notion that the Devs wouldn't make something that stupid available in every run, so when I first saw Conversion Stone it never crossed my mind that they'd make something like that lockerable. How wrong was I.
WONNAFYT turned from insta conversion into "get a bunch of uses whtile exploring then convert" teritory. With TT around, 1-2 lvl popcorn bowls are good, stupidly good with a fighter. Now that we have healing milestones, that would be a viable strat, esecially for a TT fighter or assasin, if the thing wouldn't latch onto stuff.
Making it only work on non-slowed enemies could be an easy way to fix this.
If it's fixed, and if the price is reduced to say 4 mana, it would possibly even break TT fighter (who is allready quite good, people just aren't using him enough).
EDIT: It wouldn't break anything as it's a glyph based strat, and would probably require as much scumming as cydstep strats do, but it would make one "adapt to unconisdered blessing from RNG on the fly" strat available. It would certanly add the fighter to the list of classes I'm cheezng on my minimalist profile as I have all the compnents unlocked, and the Gaan'Telet diploma of kicking asses with Fighter ^^
