I've watched that video and it was pretty laughably biased in favor of the spear. Literally did like 20 matches of 1h no shield vs spear (where spear has MASSIVE advantage) but then when they swap to shield vs spear and they sweep every match they only do like 6 or 7 matches before quickly swapping. They just let spears run up the score when they have the advantage and change it so when they dont. In the group fights, why were the swords all 2h and not 1h and shield? Wonder how that fight would have went.
It was also really obvious none of them had ever really fought with shields before either. All in all, a shit video.
Also, polearms is already arguably the best class in cRPG so dont see why they need a buff. I just recently swapped from 2h to pole and holy fuck its so easy to rack up kills
