what professions to prioritize?
I would actually lean towards Thief/Daredevil.
Why? Because you’re going to want to get into places in the new zones to get Mastery Points and start unlocking access to the mastery lines in HoT. I’m unsure of if they’ll add any Mastery Point locations into main Tyria as well, but I guess they might.
It would be a shame to run out of points and “waste” EXP until you can find more to keep your masteries going. I figure Daredevil will be the class of choice for getting into and out of interesting spots to tag MP locations.
delicate, brick-like subtlety.
I think the more important thing is to prepare your gear for the new specializations (if you’re into that sort of thing). As I main an engineer, that will be my first to unlock. I just got my warrior’s weapon smithing level to 500 last night to craft a new ascended hammer. Fully upgraded and ready for action when my engineer comes calling.
Following that, I’m not sure who would be next on my list. I have decked out necro, ranger, and warrior. I don’t play them much, so I’ll just work on them when I feel like taking a break from my engineer. I will say this though. I’ve never quite liked the mesmer profession, but the new chronomancer specialization looks cool and I’m looking forward to seeing how that plays out in WvW.
