A couple things need to be tweeked imo to add a bit more reality/competitiveness to pvp.

First off ... Number marks need to be removed on death. This would help Healer classes actually WANT to heal in pvp. But when the opposing team can just mark the opponents healer and even after they die they are still marked so everyone can just pounce on them again it's not right.

Remove Class indicators for the other side. This goes along with the marks if I am in a premade and I can tab to see which of your team are clerics I can auto target them before the match even starts.

In a battle/war you have to ascertain this information ON THE FIELD.

For those that ***** about the marks during pve ... takes 2 sec to re-put them on vs letting an abusive mechanic remain.
