I find vocals one of the easiest things to process. I spend much MUCH longer getting the bass/guitar relationship right.
If you have a good chain, a good vocalist, a good performance and a good monitoring system then the EQ will basically do itself. One thing that really helps on vocals is outboard. I've tried a variety of plug-ins over the years, but recently switched to using my Millennia Origin and 1176 A because they work really well in conjunction with certain plug-ins. Plug-ins are still useful for de-Ess, multiband, limiting and more stacked compression.
Stacked compression is probably a key word with vocals. I tend to use maybe 4 or 5 dynamics controlling tools by the time the vocal chain is done. It's ok to be very aggressive here. After you're done slamming them you'll find all the nuance and character is right in your face, so all you need to do is saturate lightly (or heavily, depending on the mix and your desires) and it'll be both crunchy and in-your-face.
One thing I'd recommend, if you're stuck ITB, is using Nebula for high-end boosts. It does that better than any plug-ins. I've done a variety of shoot-outs, and nothing has touched some of the analoginthebox and Alex B EQ programs (apart from the Millennia hardware of course). I only realized too late that the Waves EQs suck, especially the SSL series. Really easy way to see why is to get any of the Waves SSL EQs and dime the high end and listen to what happens. Then get the Nebula Massive Passive or API master EQ programs, dime the high-end on those and listen to what happens again. You start to see after this why too much high boosting on ITB EQs will make your high mids brittle and harsh. It's quite an enlightening experience.
But no, I don't think I would ever not EQ vocals. It's like those people that say they don't EQ their rhythm guitars at all in their mix and then you listen to it and it just sounds like horseshit. There is natural junk in almost every signal we record. Not saying I advocate drastically changing the spectrum, but changes in the realm of a dB or a few are perfectly normal. Having a 'perfect' vocal sound on the way in would be like having all the planets align then give birth to a shotgun out my peehole.
