I'd really like to see some more AoE heals for combat medic. I was playing a 16 man story mode last night that could have used more than just my kolto grenade. We had 2 other healers but none of them were sages and I just kept throwing out my grenade like it was going out of style.
As a DPS, I haven't even tried PvP because of my gunnery tree. Even in duels I get interrupted constantly which makes it quite difficult to do anything. I think a nice change would be to make grav round cast faster the more times you use it. So for example, my rotation is Full Auto > High Impact Bolt > Demo Round > Grav Round until Full Auto procs. My average usage of grav round to get full auto up is 2-3. So maybe after the first grav round, the next one can be casted 25% faster, then after that casted 50% faster, and the maximum being 75% faster casting which could stay as a buff for like 30 seconds or something. Most everything else can insta cast so it's just the full auto and grav round that get stuck when it comes to any sort of pvp.
Also for the gunnery tree, it'd be cool if we didn't have so many useless things we had to put points in for the next branch to open up. Off the top of my head, Decoy and Heavy Trooper are the most useless (are we suppose to be tanking? lol). I think advance the line, concussive force, and tenacious defense are pretty useless too but less so. I really only took them so the next line of skills would open up, and my leftover points went into other trees.
Another point I'd like to hit, we run really slow and hold the line literally looks like it makes us run at normal speed. I am always at the back of the op watching the shadows and whatnot run further and further away. Ops groups always have to wait, and god forbid us commandos are trying to farm mats because then they have to wait even longer!
Lastly, I didn't even level in gunnery tree, I leveled as an assault specialist and when I hit max I was told I had to change because they just don't rank as well as the gunnery (not saying they suck, just telling you what I was told) as far as DPS goes. I really liked being an assault specialist with all the explosions and fire so please do something about that tree (make it more like vanguard DPS or whatever) so I can go back to being like Scorch from Delta Squad.
