This actually seems perfectly fine to me.
Yes there are some weird "glitches" which are a part of gameplay, nothing you haven't seen before in a movie.
Not on the realism board, remember? And these moves are TOUGH to get off. If you've got a team around you, even the pro-est of the pros will be hesitant.
I have seen multiple pikes used to great advantage, and I've seen them destroyed on subsequent rounds.
Pike users are in big trouble if somebody just downblocks, or approaches with a shield. There's your counter.
Long spears and such weapons with side-swings and overheads are still fairly slow enough that it should be easier to block than many other weapons. It's not as though they have crushthrough and knockdown like a maul - as in they can be LITERALLY impossible to block.
