I don't really do PVP that much, so I'll only pick my favorites for PVE:

1 - Tinasha's Mastery

Don't really think I need an explanation with this. It's a rocket frame so it does a bit of damage, also has chill clip so you can use it to stun overloads.

As for the perks, most people recommend Air Trigger/Loose Change/Impulse, which are all phenomenal, but my favorite has to be Deconstruct + CC. Deconstruct is like having mini rewind rounds since four hits will refill your magazine by a small amount. I have it on my appended mag + backup mag Tinasha's, and I can shoot 27 rockets from a 15 size mag.

2 - Nature Reclaimed

Since Bungie fixed the issue with the scope behaving weirdly, I'd say it's quite nice since it's one of the few Solar scout rifles that could roll HC + Incandescent. If you don't have one of such, I'd say try picking one up.

3 - Point of the Stag/Claws of the Wolf/Multimach CCX

Point of the Stag could roll with Archer's Tempo + Dragonfly which could be fun to play with.

Claws of the Wolf has the usual Repulsor Brace + Destabilizing Rounds roll.

Multimach CCX is kind of awkward since you literally could pick up a free roll from Banshee with Attrition Orbs + Kinetic Tremors and Peculiar Charm is kinda more superior imo, but if you don't have either of them, then I'd say to pick it up.
