I think perhaps certain abilities warrant a more subtle touch when it comes to their visual effects. Considering that in all other star wars media, the Force is almost always formless (with the exception of lightning and whatnot), a lot of the abilities ingame feel downright immersion breaking.
Do Sentinels REALLY need to glow so much that you look like a super saiyan when at 30 stacks of centering? Do Sages need a giant "I'm a mage from WoW" bubble obscuring themselves at all times in combat? Why must a Guardian's eyes glow white for every other move? A lot of saber moves would look better without glowy force power spinning around the character. It's a laser sword, just moving it is flashy enough.
Don't get me wrong, I appreciate the work put into it and I realize that visual cues are important in some circumstances, but I think we can safely tone some of these things down without affecting that. Or even better, shift the focus to auditory cues.
