I just did a test. created a smuggler, level 6 I have one empty key with no spell on it bound to "shift-6" I walk with the character front-back-strafe left and right while spamming this "shift-6" bind. After 10 seconds or sometimes less the character will crouch for cover... and no command was actually pressed beside movement since shift-6 is empty.

I have the same issue on two characters and it seems that the ability bound to "1" is triggered even when 1 is not pressed.

I personnaly stopped playing my sith sorcerer at 32. Abilities not casting while the GCD shows they are ready. Character showing a cast animation and no damage is done. Abilities going on GCD while the character does nothing. Abilities cancelling for no reason and having to recast while the character was stationary the entire time. On my jedi shadow 25, too often I find the character locked in a animation and being unable to chain a second ability. The game is just not giving the smooth combat I am expecting from the UI feedback I am seeing.

Seriously... stop making yourself look bad. I have reroll every single class but one passed level 10 looking for one class where this issue is not flagrant, to no avail. Unless this is fixed and fast it is unlikely that I will continue. The game and story are brilliant, the combat issue makes me pull my hair every time I am facing a mob.

Folks this is the same kind of entitlements that has killed many mmos and one that is killing wow.

I played a sith assassins until level 24 and the issue of abilities not firing up while the global cooldown was already finished was real bad. I play on a top end computer with a very good internet connection (30 ms on average). This issue is very bad for melee. Having to wait for an animation to finish prior to being able to launch a new ability is clearly a big issue. There is no way I will be moving my guild in swtor for high end pve with such glaring combat issues. I also leveled a sith inquisitor in order to see if I had the same issue with a caster. I noticed the same issue: casting animation not playing while the CD is used and no damage done. casting animation not playing and damage given. queing of abilities messing things and the wrong ability being cast. This was most noticeable in instances. I cannot stress enough that combat as is is clunky and unresponsive. As is this is the TOP issue that need sorting out before any end game addition. If combat is not engaging and extremely responsive, then this game will be just a solo game with a few group content.
