Here's the problems with LS/Pike:
1) spinning your body in this game gives the weapon speed, so people will do it to get the most deadly hit. It makes sense for most weapons, but looks ridiculous for the LS/Pike. Unfortunately there is really little to be done about this.
2) The LS/Pike can be blocked by a guy just holding block down. In fact, three LS together can now only stab, so they can all be stopped by one backpeddling 2her. It is COMPLETELY UNREALISTIC that spears only stab in one direction. Both LS and Pike should have an alternate weapon mode (press x to toggle) where the animation changes and their poke becomes high piercing attack. That way two Pikemen don't get raped by a block-downer, which makes NO SENSE since the Pike was a defensive Teamwork Weapon.
Right now, the spinning happens because the "leet dudes" know that if you turn your back on a guy he will let his block go and prime a swing, and that's your only chance to get past his Down Block. So if the LS/Pike weren't as GIMPED by the #2, perhaps the #1 wouldn't be the only way to success with the weapon.
