Not really. You could try. 0% increase attack speed is just... 0% increase. Same goes to regenerations, armor gain, damage boost etc. In these cases, 0 does not mean infinite..
Some other things to look out for are Immolation Duration (don't set the time to 0) and Phoenix Fire Cooldown (don't set to 0).
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
