There's a lot of combat animation issues in this game, which never had any business getting past QA dating back to the beta, but yet here we are... crappy combat bugs and all! In all seriousness, anyone with an ounce of competitive PvP blood in their body knows exactly what you're referring to. It's crappy and is a glaring problem at the core of the combat system that I don't think will ever be resolved or else it would have been done back in beta. Welcome to SWTOR!
