It's nice that you (the Commando devs) are trying to get a nice rotation going for the Gunnery tree, but in all reality, there needs to be a better reason to use charged bolts than the fact that it does slightly more damage. The worst thing in the world is knowing that you have to hit 8 buttons instead of 4, because the extra 4 you're hitting don't apply a debuff, but do slightly more damage. This isn't really a real rotation, and more poor design for bad skills. There's actually no reason at all to have grav round. You could just make the original talent for grav round to give charged bolts the armor debuff. Also, Full Auto is a pretty underwhelming ability until you've talented into it (the talents are very high in the Gunnery Tree), making leveling a massive spam fest of Grav Round and High Impact Bolt and some other instant cast abilities. What's more is, if you take 1 hit whilst channeling full auto, you seem to only attack twice, instead of the original 3. What's this have to do with anything? Well, it basically just comes back to spamming grav round / charged bolts to level since it's the highest single target damage in comparison to ammo / cooldown. Which is bad- Of course.
