They clearly wanted combat to look good, and it does. But unfortunately, in PvP, you very quickly learn to care only about your performance.
I'm not sure why they insisted on long GCD and slow animations for PvP, but I think they made a very bad choice there.
What's worse is the sound design. A strong PvP game NEEDS clear indicators for every key ability - and especially CC effects. That goes for distinct sound effects AND visual effects.
That your character looks cool when slashing someone with his lightsaber is totally useless if the delay between pushing the button and the effect happening takes more than a second.
Then again, most MMOs mess this up. WAR and RIFT were both very clunky in this way as well.
You need a keen insight into game design to understand these finer points, and Bioware clearly doesn't have what it takes in this area.
Thankfully, the game is pretty good for what it is - a largely story-driven linear experience.
