Some "new" overhand animation for all spears(those used with shields especially - if there is such a animation) would make game more realistic - spears, etc. were always used by majority, because they're cheap, easy to use and deadly - and challenging for all imba 2h/pole, because they couldn't just block down all the time... and current overhead animation looks really stupid, while using spears.
But I don't think deluge team would share it and taking it from WFAS is illegal.
