Guys, dumb question: in what type of build is attack speed bad?
I've seen a few people mention it with regard to certain skills in their build, but I'm not really clear in how AS punishes things like Disintegrate. Also, does it hurt other channeling abilities like Arcane Torrent? I'm not having resource issues because with "arcane on crit" I crit enough to sustain it almost permanently. I didn't find the same to be true with disintegrate, though. Almost like it wasn't really critting? Or very infrequently.
Just look at it this way - if you can obtain the same amount of damage elswhere, it's almost always a good idea (unless you have something that explicitly benefits from ASPD like WD's Fetish Syncopaths) - ASPD technically increases your DPS but doesn't do a thing for resource efficiency. Say you went from 250k DPS to 500k DPS SOLELY on ASPD. Well, shit, your arcane orb used to hit for 250k and crit for 1m and guess what, it still hits for 250k and crits for 1m. And you still can cast just 4 of them on your arcane power pool.
Then the other stuff kicks in, like, you're able to dish out the damage faster and you didn't really sacrifice anything, and you're able to squeeze in a couple signature spells, and if you use Prodigy that's gonna generate AP faster too because you cast more of them magic missiles or whatever. So yeah, you did increase your sheet DPS as well as your actual DPS. But not nearly by 100%.
Now take the same situation - you increase your DPS using anything other than ASPD, let's say you bump it again from 250k to 500k. But now your attacks crit harder, more often, or just do straight up more damage. You can safely assume that your real DPS has just doubled.
To top this little lecture off, enter Crusader. Half of your fucking skills are on cooldown. You don't give a crap about ASPD, not if you'd have to sacrifice anything else to gain it.
