The bloodsail captain RE seems to lean heavily towards parry as the main focus with the 20% agility conversion to parry rating. And it works nicely with the Matched blows RE for swashbuckling. The image behind this RE is of an epic sea captain deflecting every single blow that comes their way.
Right now I run with Matched blows, emanating light, and Ghostly strike/earthborer acid.
How does In the zone scale? It doesn't really mention how much damage the bubble can eat. Is it just however much damage is dealt via unfair advantage? That would be noticeably lower when using a 1h vs 2h weapon.
I realize there are other RE's out there, but those RE's are available to all tanks. (I also don't want to dump 2 talent points into what is essentially a talent to increase damage unless its really great)
Ghostly Strike adds 10% to dodge when used, or parry if you're using a 2h weapon. 10% bonus parry would be much more useful than 10% dodge. Especially when paired up with the deflection capstone (which i dont believe should be limited to 2h weapons either).
Now, perhaps the 33% of parry chance reduction on direct spell damage combined with the 8% from flurry of blows would be OP. Fair, but that 8% is static while the deflection talent scales with gear.
Also, considering that shield tanks can use abilities like spell reflection and the shield cover talents to boost their spell mitigation by 30%. I dont think having 15% ish from gear is unbalanced.
Honestly, i think most would choose parry, since in pvp, overpower makes having more dodge a liability. and tanks that would use it are either parry focused with 2h or swashbuckling, or are bears and unable to use ghostly strike in their forms.
