Whirlwind

[Heroelite]

This skill is one of the most useful for mob killing with warrior but I think it shouldn't have a 3 target limit with each strike. It would make more sense if it just hit all enemies within the 4-6m.

That would make it far too powerful relative to the other possible attacks.

Still, I don't think that WW is necessarily a better choice than Chest Splitter for pure tank builds because CS provides interrupts, knockbacks, and only has a 3-sec cooldown. WW isn't necessary to hold aggro with Horn and CS (and especially if you also have taunt speced under Juggernaut). Since Warrior's do such little damage relative to the other two classes, I'm happy provided tanking and interrupt/knockback services while everyone else DPSes.
