In the context of a quick fix before t5 or raid release... What quick and fast changes could be implemented for a tanking warden to make it desirable for harder content?
Pretty much most people agree that captain spot is 100% not in debate for one tanking spot since they bring an insane amount of support to the group, so then changes would need to be focused on making wardens an alternative to guardians. What's your ideas? Mine are:

1: rework a bit Never surrender skill in blue line. Basically it's decent for a dps role but terrible as a tanking emergency skill. I would suggest reducing the cool down by another 2 minutes at least in blue line and make it apply a defensive buff for 15-20s after it's triggered. (Something like -40% Inc damage or avoidance buff or incoming healing buff, just something significant in% so when something goes wrong in the middle of the fight and you use that NS you get some survivability for a short while rather than just one big heal which is worth 2s of boss damage).

2: an extra click able emergency skill which gives some defence for a while, something like guardian's pledge or similar.

So what are warden community suggestions?
Try to keep it as something quick or simple so there is a chance to make changes in a small update rather than having to wait years to see it implemented. Not exactly a revamp post about how to make blue wardens good or enjoyable but rather just a quick fix to make them viable.
