If the shoe fits.....
Kinda funny you insult us for insulting Pretty hypocritical dont you think? Either way I've provided some valid points that shows I do not lack in the grey matter as you claim
But seriously, removing tanks would dumb down PVP. Tanks add another element to the game other than just derp smash. Learning to cc tanks when you want to burst someone so they cant switch guard, pulling/pushing/knocking the tank away so you can kill someone. Being able to do these things is what sets apart the mediocre teams from the good teams.
And on a side note, even WoWs PVPers ask for tanks to be viable in PVP, just check their forums.
