So, you're arguing that an ability that doesn't hit harder than the primary spec abilities, can only be used on week/normal mobs, and is useless in all the important content is a big deal? At 49 my annihilates were doing 2k+ non crit, and at 49-50 even Vslash wouldn't be far behind what you're calling your biggest his with savage kick, only with no setup, and it works everywhere.
Sounds to me like you turned your back on dps some time ago.
