Tracer Missile used to use Fusion Missile animation and vice-versa, so people spamming Tracer Missile were basically spamming the Butt-Missile. Heck, someone even edited a clip of Episode 2 to give us this gem:
I finally logged on my commando just earlier to test him out after a long absence and I do agree, HIB is very underwhelming, like most of the animations. You guys get Stockstrike as the Republic version of Rocket Punch, right? Yeah, even your out-of-battle-healing animation looks like garbage. It makes sense, but still boring. I might play my Trooper more of the animations didn't bore me to tears, and I normally don't even consider animations as something to consider, but this is a Star Wars game, I'm not used to being bored.
