Only until you start to abuse the geography to turn the 5-spread into 4,3, or 2 spreads populated by multiple enemies.
Doing a GSed Heaven Knight SCC will give you a whole new appreciation for the class. Easily one of the most interesting and fun SCCs you'll ever do. Makes you really take a look at the maps in a way even the Geomancer SCC doesn't do.
Yeah, the geo restrictions assist in targeting of the skill and I know it can hit hard 5-6 (?) times.
Crap, I can't remember right in regard to reflect mail and shenanigans with this spell or not...
What I was getting at though, was the times where it hits once or twice making it not seem as cool as it can be potentially rendering the random element annoying to deal with.
Conversely, breaking the game via SPD and just simply commencing the unholy melee beat down on folks is sooooo much easier. It is less visually satisfying though.
