This is a great plugin, our players are loving it. i do have a couple of suggestions:
1- Add the ability to lock players out of raid for a period of time with a command (/lockout id time for example) so that admins can lock players out that cause troubleat raids, we have trouble on our pve server with others getting in the way at raids that arent theirs.
2- Add the option to have more tiers, on our server we would like to bump it up to at least 5 levels of difficulty.
Thanks again for an awesome plugin
