Void walker is the way to go

Fusion grenade with Starfire protocol and either self resurection or damage reducer. I also use the initial jump boost. Gets me or of tight situations real quick

Shoot things

Use the power glide. It's the third unlock. With that you can get places nobody can on one jump. Also the jump is different than the Titan. To maximize your verticales, double tap jump as fast as possible. And also to avoid from gliding in the air forever, tap jump a third to to cancel ascensión for a more precise landing. Regarding Void Vs Solar subclass. I love then both and they both have pros and cons. Most nubs will say go for the self res. But the Void is a lot of fun so explore to see what fits you. Also the Void class has slightly better Agility and the sunsinger class has better up close and person armour.

Go sunsinger first unless u have obsidian mind and bad juju
