I can agree with this. Every pvp player uses the same brim/ hybrid/ nuke build. Litteraly everyone. Its the only build that does hard damage. I myself dont use any of those besides brim, so maybe thats why i dont constanly and easily kill people in quick successions. I can make decent kills with my long time same build without using bless or aura, but nothing like the people that use these same tactics with the same builds with everyone doing the same exact thing. Also it can be too easy to be next to people that gets hit with these same combos, and others right there just finish them off easy, making it a bit OP and just feels a little cheap and repetitive.
Maybe make some other skills stronger or even add some brand new skills.
Im not one to complain and hope im not coming across as doing so but you have very few choices for pvp which is either use the same 3 skills or just die over and over and over by those skills in the same exact ways by the same exact skills.
