I did and didn't like the feel of the subclass it self, it didn't feel like a fun subclass. Even watching titans it seems they succeed with FoH more than they do getting shut down themselves. So yah I know, even without playing it much I can still say from Dying to FoH so damned much that its one of the hardest supers to shut down unless you get really lucky (like forgetting you have Celestial nighthawk equipped and destroy that unfortunate titan mid super and stand there confused as to what the hell just happened lucky).

No, you can't intelligently comment on a subclass you don't use. If you did use it you would know it has plenty of weaknesses, just like every super.
