Warriors are actually the best choice for res signets because they only need one or two adrenal skills to max out their damage over time. They should have more slots free than most other characters.
Its always an interesting discussion when it comes to whether or not monks should bring a res sig. After all they are almost always the first to die, and they always get repeat killed as soon as they get ressed because of their ability to keep others alive. Then again usually a monk can spend 3 seconds to res somone as soon as they die without having anyone else die. And they can res as soon as they get ressed to get your team up.
I bring a signet of ressurection into random battles, etc. for the sole pupose of being able to ressurect one person, and when I'm the only one with the signet, and someone else dies, I can go "I used my signet, fool, where's yours?"
And its always warriors who dont take it, gives us a bad name.
Considering we warriors do less damage, get attacked less and are less likely to be interupted than some other classes were the ones that have NO excuse not to take it.
I mean ive spoken to people who take a executioners strike over res, thats a +30 damage attack over a res signet that brings em back to full health.
+30 damage
what use is that going to be.
If you see executioner's as only +30 damage you don't understand adren spiking.
The truth is most people don't understand the game very well so just having them take a res signet is good. However res sigs can be countered. When I play an axe warrior I look for the res sig and attempt to hit it with distrupting chop.
It is a gamble, you sacrifice a slot (which can be very powerful), but in turn gain the ability to rapidly bring back a teammate. Due to team sizes the res sig tends to be very powerful in 4v4. In 8v8 things are far different, if you put 8 res sigs on you just sacrificed 8 skills. Plus in all the 8v8 modes there is a method to get morale boosts stretching your res sigs further. Thus you need to determine who can sacrifice a skill for a quick res without hurting their build too much. In PvE it really doesn't matter, you can get away with practically anything. You have to weigh the gain of a res sig vs what you can do with your other skill slots.
