I see absolutely no reason why PLD shouldn't get circle slash back (hopefully with an enmity combo bonus). War Drum and Flash are clearly not enough to hold hate on a pack of mobs for anything longer than the first few seconds of a fight (there are also other significant issues with us having only 2 reliable AoE threat tools on longish cooldowns), and it's not like our AoE damage is going to be anywhere near Warrior's.
It's one thing for WAR to have a situational advantage over PLD (AoE Tanking/AoE Damage), but another entirely to have PLD be comparatively ineffective for a very important role (AoE threat and generating snap aggro on multiple incoming mobs). It does not make sense for a premier and specialized tank to be so powerless in a very important scenario.
TLDR; War Drum is an under-tuned ability by any metric (this needs to be buffed regardless of what you add to the class), and Circle Slash would be a welcome and reasonable addition to PLD's arsenal.
