I agree with this, but it is also the one thing that can instantly shut down a wizzies ability to spam tempest, if you get puri'd as a wizz you must recast shield at the least, preventing you from chucking down more tempests. It's something that I thought needed changing but the more I looked into it, actually balances/counters out the wizard tempest in some aspect.
Melee on the other hand have no such option, but I am honestly fine with that considering if a melee does get up close it's usually instant K.O, people moan tao's are OP, and they basically are, but they're the corner stone of balance in group fights and I'm wary on buffing or nerfing them further.
I do like some of these suggestions though. The clock is something I think we could add. Then again it's in our favour to have you guys lose track of the time and keep playing :lol
As for a never-ending dungeon, Jamie was working on something along those lines last I checked... however it was a little OTT and it got put on the back burner.
Quests are something we can do, but do you want meaningful quests (would take time) or just throw a bunch of new/easy quests in?
