I'm noticing a trend where my game DC's just when Karka Queen is about to die.
I always have a soft crash (the game crashes to desktop, but I can get back into the game, but without any audio) at Tequatl, it's something in my graphics settings that bugs out because when I set them to best performance I'm fine. Try that?
So what's the best way to gear at 80? Is the trading post exotic gear the best or is it possible to save some gold and use karma for some parts?
You can go with the following;
Badges of Honor (WvW)
Reward Tracks (PVP)
Gold (Trading Post)
Karma (Orr Temples)
Crafting
Dungeon Tokens (not Fractals though)
Commendations (Guild Missions, Weapons only)
Laurels (Profession gear boxes, chance for rare or exotic though so it's a gamble).
RNG (Flush rares in the mystic forge and pray to RNGesus or hope you just get a random drop)
Best way will depend on how much of those currencies / materials you have stockpiled and how much you want to press your luck with those last two. I find the easiest tends to be Karma since you generate a lot of it for everything but rarely spend it.
I hope guild missions went smoothly. Did you guys end up karka rushing?
Save our Supplies challenge (made much easier by the presence of another guild).
Sotzz the Scallywag for bounty (found him really quick, but waited for a second guild to join us for the kill).
Proxemics Lab puzzle, nice and smooth.
Baby Bear rush, also went very nicely.
Missions were done just slightly over an hour after they started. Saturdays always feel like a mad rush, I love Sundays where things are a tad slower paced, we can take time to explain stuff... definitely a nice change of pace between the two times.
