Warden HoT's were nerfed into the ground for redline, it's the blue line that currently needs a bit of DPS reduction.
I maintain the stance that damage output should never reach the point where guard is even mildly competitive DPS for instances, it is the tank class, it has 2 trait lines that tank very well. If third traitlines are supposed to be competitive in groups then guardian is one of the last classes requiring buffs to make that possible.
As Red Warden (currently level 91);
1. My morale is really low, battle memory and use 2 Resolutions for burst healing.
2. As I'm rounding up monsters tap every mob with EoB.
3. Need more morale from tabs, through in a Fierce Resolve.
4. Still need more morale, throw in a Restoration and Conviction.
When combined with Defiant Challenge with only 10s downtime, god mode.
5. Still taking too much damage? Throw in some avoidance gambits.
There's no need for me to drop into Blue when soloing instances at the moment because of Defiant Challenge, access to all gambit heals and taps, and parry heals.
Please, please keep talking as you are doing yourself no favours.
