Do i REALLY have to explain how various sub-classes within the polearm category work?
Pike, Long awlpike, English bill, Ashwood pike, Awlpike, Swiss Halberd - these are the pike type polearms, that are best in group fights to support others by stabbing at long range. These are not 1v1 spammers (usually, anyway, the last 2 can be used for that, though).
Comparing them to other polearms is generally the same as comparing 1h to 2h. I think the pokers are near OP, certainly not underpowered. What could be done is looking at the INNER balance of the pokers, but i think that is fine too, except for perhaps the ashwood pike, that seems kind of bad to me.
