Yes but that messes up Invoker. The 4 points in Quas were perfect - 2 forge spirits and perfect tornado timing for the meatball. Now if you add more points to quas, it messes that up (units are suspended in the air longer).The damage is based on lvls in Quas now thus you might need to change the build a little
The biggest issue is that the coldsnap + autoattack combo does very little damage now at earlier levels.
