I realise this was tweaked to fix a bug with bot mana, but this is really killing us when we want to refresh buffs during a clear. Due to server population it is very hard to have all the classes you want during a clear, I think a 1 minute recast would be more fair then the 3 minutes it is currently.
This would save us from standing around waiting for a bot recast but would not enable any less than ideal problems.
