@Mythra Thanks for the reply so quickly I am looking forward to checking out your server when it goes live.
1A. Personally I don't think the CC's should be gone outright maybe work them into a set bonus on a super hard boss with a low drop rate and give them a lot less chance to proc. The problem with them in my opinion on Zircon was that it made Casters too powerful more so the wizard who has tempest which gave them twice as much chance to proc. (And them stats where never designed to work with casters)
1B. As for Evasion and Block I also think these stats are a good thing and fit very well with the shields but again the % can't be too high or it effects both PVP/PVE too much.
2. That sounds a lot more balanced than potions you can spam endlessly that don't even have a weight.
3. The issue with it was that it required no skill to use, removed every buff in an AOE, had no cool-down, and could work against players a higher level. Against a wizard they could cast it once's massively reducing a wizards DPS and removing there only defensive buff and because it was AOE it's super easy to Aim. There was debits about how to fix it for months on Zircon and even the Taoists playing the server said it was too powerful.
