To answer your question more thoroughly, all the skills (lvl 0, 30, 60, 90, 100) for spears have not yet been implemented. You can, however, use them in-game and they are highly effective against full plated toons running around with big swords
I do, however, find the spears to be somewhat low damage, but I'm pretty sure I had a crappy quality on all the spears (if that even matters). You should rush lv 90 spear mastery and go for the Bec De Corbin as it deals ALOT of piercing damage if you hit the enemy with the little spike thing on the end of it. Good luck!
