Marauder/WAR issue is simple, all the combos do the same amount of damage about(from what I saw when fighting Ifrit) but the front combo is the most efficient in recast and TP cost.

Front combo is a simple recast of 10/30/30 second, side combo is 20/30/60 and back combo is 30/80. Then the TP cost to start each combo is 1k/1.5k/1.5k. What makes the back combo even more horrid is the ridiculous animation lock you suffer when using the ability, it just doesn't make it an efficient AOE like Steel Cyclone currently is.

I think one adjustment that might be interesting but it may be asking for to much is if they made Steel cyclone a front and back combo, however the combo only works if you have the proper stance active

-Change Steel Cyclone to a 45 second rest-
Front Combo=Rampage active:increases enmity gains lowers dmg and decreased recast by 15 second
Back Combo=Berserk Active:Increases Dmg/Crit hit rate resets Berserk effect increase recast by 15

So perhaps combo wise the recast should be
Front:10/30/30
Side:20/30/60
Back:30/40/60

Have the back attack Steel Cyclone do the amount of dmg it does now with a front attack combo and make the front combo one a means to gain AOE enmity rather then something that deals heavy dmg. Paladin have War Drum so they can easily gain AOE enmity whenever they block and it's up along with AOE flash, so if it's possible to make Steel Cyclone both a DD/tank ability depending on which combo you use it from I think it would balance them out properly.

Whatever changes they make though, I just hope it doesn't make the idea of a War tank obsolete.
