I just leveled one to 50 after a lot of alts lol. It was a really fun ride, one of which I encourage you to stick with. I second venom grenade, since it's a big dps upgrade. It does considerable damage, and the -res is really what you want. I'm personally working on acquiring the ios to get perm hasten/pets, but in the mean time I love feeling like I'm an asset to any team with the strong buffs/debuffs I bring to any group. Also I did the first strike force (forget the name), with 3 other soldiers and our team was softcapped and the avs just melted. It's one AT that the more you have the merrier.
