boosting casting speed for sorceries is a waste

I was flabbergasted when I finished putting those animations next to each other: only dark moon seems to gain a tiny little bit at 52dex+radagon (so essentially 82 dexterity so cap long passed as it caps at 70 according to previous research by others) compared to basic 18 dex and the fast pewpews also. but really not by much and I would argue certainly not enough to justify using a talisman or putting 50 more levels in dexterity...
it is disappointing but also a relief because at least now I know that aiming at increasing casting speed is a waste of effort. I would have expected the casting speed boosts to affect charged spells a lot more but nah.

I've tried pure int and int/dex builds and the speed difference is noticeable but not worth the tradeoff if spells are your primary means of attack

The only benefit is like what 1 second? and you spend over 50 points in dex good job
