Only thing wrong with Northstar is that the Flight Core seems to have a really long ttk relative to the other Titans' core abilities, and it leaves the most fragile Titan a sitting (well, hovering) duck while they're using it.
No way, dude. Northstar's bread and butter is luring people into tether traps and then lighting them up with a Cluster missile while they're stuck.They should give Northstar the particle wall and Tone the trap.
