Rhymer is a crutch, play without Demolisher, Bwings are OP, Gallant Heaven is unbeatable......seriously.
There is NO SUCH THING AS A CRUTCH.
Everything in this game is simply a tool, to be used to its maximum efficacy so as to blow your opponents plastic ships. Yes, some are used more than others. But I have yet to see something so overwhelmingly OP (talking about current state, not wave 1) that it cannot be countered by proper planning and admiralty.
If your rear end hurts because someone spanked it hard with some crazy combo, quit whining about it being 'OP'. Put on your big boy pants and develop a strategy to counter it.
Admiral Wolf out.
