Spellspeed won't lose it's value on BLM, simply because your whole damage is still tied purely on a Spell by Spell basis. It won't be as good, just won't be worthless either. People might actually just find a sweet spot for it.

They want for have multiple buttons on PvE be something of PvE and the minimalistic button setting to be something that is PvP only. I'm ok with this.
