What I think they will try to nerf is /castsequence with commas for timing
Yeah, I wouldnt be surprised.

This is kinda why in EQ my stratagy was to pick a class based upon a single spell that I planed to spam. Cleric for CH for example.
Ah, good 'ol EQ1. Back in the day when my wife and I used to each 3-box EQ1 we were unaware of things like key broadcasts and we had to be constantly tabbing between windows to cast spell :P Though combat there was alot slower paced than modern MMOs.
