I didnt get a chance to actually test the new system very much and wont really be able to for a few weeks yet. However, while in EQ today ( to check my stuff as I have had stuff diappear after patches in the past) I over heard a conversation in OOC.
There were many people in POK seeking KEI. Ordinarily, this is quite common on my server as I am sure it is on everyone elses'. Someone replied that they think KEI is kinda obsolete now the new mana regen system is in place. I kinda agreed because I had been wondering about that point myself.
One of the seekers of KEI replied back that the system works while resting, but that she still needed KEI to regen mana while in combat (she is a high level cleric ). This too made sense to me.
Again not having tested the system, Im not sure what to think about it. Is it safe to assume that while in combat, mana regen was the same as it always was and the only change applies to while resting?
