Besides ferrets, There is still one thing missing from the update... Mitigation.
Ghamp is a nemesis troll that you can find hanging around Limlight Gorge.
Im sitting here on my warden staring down a nemesis and of course...

Challenge Accepted
Things were going great! He gets a buff that gives him a huge boost to crit chance and i was pretty quick to remove it everytime it came up. It came up once when i had him to about 11k morale when all of a sudden i didnt remove it in time.
BAM!
The Ghâmp scored a critical hit with Critical Onslaught on Krackus for 11,219 Common damage to Morale.

Ok i know soloing a nemesis is a little overpowered but we will be expected to take hits like this when tanking in raids as well. The mitigation issue is still there and there just isnt anything we have that can counter spike damage like that. If im sitting above 10k morale im not so worried that i need to go ahead and pop NS...

The above mentioned hit killed me. Taking on Ghamp was incredibly fun and i plan on doing it again soon! Until that point i felt in control of the fight and things were going great! Just an example of how we feel strong against everything but spike damage and why guards will still be preferred in raids.
