Should I keep swapping equipment as they reach 100 spec or use the same gear over and over?

Hey everyone, I am part of a guild but I do a lot of solo roaming, doing solo camps, killing roaming mobs and doing the occasional tracking. I'm almost at level 100 with every gear that I have (except for my weapon, the Longbow, that is already at 100+) and I'm wondering what's the best course of action for when I get to 100 spec.

Should I swap my equipment for different gear and spec them up the same way? I'm talking about black zone, by the way.
