In arena, I feel like it's hard to do switches if the target I was previously on has 5 stacks of Seal of Truth debuff on them which will break any cc I try to throw up other than HoJ. (i.e. repentance). There are way too many times where I need the target to sit in a full repentance so I can recover or switch to another target. Also, Seal of Justice brings a pretty nice effect to classes such as Druids, Rogues, Shamans, mounted players, ect.
I am just curious to see other's thoughts on this. No need to bash me if you think it's obvious what seal is best at the moment, but instead just let me know by a little feedback. Thank you guys! :)
