Well, I think it was both Rogue and Cydstepp there - Cydstepp lets anyone ignore health completely as long as he can pay around 10 mana. It's too good an effect, and I'm using the current Cydstep and prepping the Namtars Ward all the time, so I don't feel like I lost out there. I personaly like my damage dealers minding their health as opposed to mana, and the mechanic was very much too good to have on a repeatable glyph. Walking in on CYDSTEP meant you could pretty much drop whatever you are doing, and go kill the boss, for quite a few guys.
Otherwise, youre right, the synergy was too huge, and the random dodge you get whenever you have a DP string is just over the top. Should've both got hit there and then. But I'm done with all this - I said all there is, too many times.
Anyone interested, I've got a few days of short PQI notes acummulating in a playthrough notes post. All the grumbling about the potions being too good wasn't baseles, so if anyone's interested, it might be worth a look.
