tank stances are a huge problems bcs are a outdated desing, any good tank tank without tank stance 99% of the time thats a fact, stance dancing is a falacy and when you face fights where you have to get in to tank stance for any reason DRK/PLD suffer much more that WAR bcs they loose not only a ogcd but resources too.
tank stances need a rework to work and have better sinergy with our other skills, in other words encourage real stance dancing more, if the penalty still stay then tank stances need to be reworked to make the pay off fair and avoid any type of desing that make it useless when you get more ilvl.
