Well this is where we say...think OUTSIDE the box.
When I left, every single one of my characters was really good at what they did, my templates didn't need any tweaking, my gear was perfect.
Then I came back...DOH! Guess what? I'm not so good anymore! I had to re-work templates, gear etc.
NOW people have to RE-THINK the way they do champs..it's really not that hard, is it?
The protector is there to insure that the people killing the champ get the max amount of scrolls possible. The protector cannot harm the boss in any way or they won't get max scrolls...now the protector can't HIT the boss, harm or heal...boring job but if you want the scrolls I guess you have to make due and figure out how to kill it without discord etc.
now granted I've been gone for awhile and I haven't done a champ spawn since I've been back, but whenever we had a protector they wouldn't even stay anywhere near the champ. Dexxors cross-healing each other, pets on it...mages for fielding and keeping others at bay...only now you're going to be keeping HEALERS at bay too.
I really don't see an issue here.
