Funny that. I play my vg hybrid and average 700k damage and 200k protection while first wz on my guardian after a few months I had 200k damage and 500k protection. You must be encountering some horribad guardians that get such low protection. Guardian will allways be the best pure tanks because of the best defensive cooldowns, the best control and the best mobility. The other tank classes do better damage but guardians can easily do 2x the protection of a sin/vg. Besides I've been in matches where on my wh tank geared shadow (recently so it's outdated gear) I have done 700k damage and 700k protection, OP QQ PLZ NERF.
