I personally like the new animation for the skill Boltstorm. However there is one issue with this that probably could be addressed with a simple fix.
It appears that it is the only commando animation that does not keep the weapon pointed at the target. Whenever paired with the utility that allows Boltstorm to be cast while moving, whenever you start moving left or right (strafing) the character simply walks as if he's not casting an ability, therefore causing his weapon to face a different direction instead of keeping it pointed at the target.
As a player that does a lot of pvp, where you want to be quite mobile, this occurs many many times during a single match.
Hopefully this issue gets addressed.
