Should I come back now or later?

[VenomSet]

Hey,

I got a few months break from the game and back then when I quitted I sold all my stuff, so now I have a total of 12m Gold to spend on gear and jewels (I don't need pets because I still have many Arc Pets)

So I'm a Rogue and already 61, is it worth coming back now and spend all my Gold on current Endgame-Gear (including Speed Sets etc) or should I wait a few months until the next expansion?
Also what's the best gear for Rogue for PvE?

Thank you in advance.
