It's honestly very good as a two directional weapon, hard to use properly, but if you pull it off it is amazing. I recently rolled a 12/27 ashwood pike on my stf, and it's the only build I can really be bothered playing. So much fun and very effective if you manage to not get shot. As a hoplite weapon it is too strong, I don't see any reason whatsoever to use a different spear than the ashwood, I think the damage should be reduced by 1 or 2.
