I honestly cant wait to try out this spec once the patch hits just to see how insane the disease damage would be.
+30% from Virulence
+100% from Contagation (put diseases onto a pet / summoned creature and spread to owner if 1v1 and if possible...in arena pretty obvious)
+30% from Ebon Plaguebringer
+8% from Ebon Plaguebringer
+30% from Mastery with my current gear (and that will increase as i pvp more)
Desecration is basically useless as long as you have one talent in DA and keep CoI up...im looking forward to it.
Basically you'd be able to get a 200% increase in damage done by diseases and all you'd be missing out on is frenzy
