Samurai's new FUKO skill is problematic, and here's why.

[Shurrikhan]

Another advantage radial AoEs have over conal is the lack of necessity for a target.

Technically, that's just a matter of not having any targetless conal AoEs as of yet. It's an advantage of a targetless AoE, which thus far all happen to be self-radial, over a targeted AoE, which can be of any shape (from-target radial, at-target conal, or at-target linear).

I would love to see the ability, such as just via Character Config, to not require targets for all but from-target radial AoEs, ideally with a command line one could use to toggle that setting. But, if given the choice between a targeted skill and a targetless skill with half its range, I'll take the slight annoyance of targeting.
