Name the dumbest thing you've done in GW.

No worries, you can freely change your secondaries later in the game.

You're most likely on the right track if you're mostly using your primary profession. It's very easy to misuse your secondary profession by trying to shoe-horn in some skills that don't complement your build or profession well at all; it's a very common newbie mistake. And, like the poster above me said, changing your secondary becomes cheap (free, if you have Prophecies) and easy later on.

Back when i was a noob,i was doing wintersday quests for the first time and i got some ectos,and i was like WTH is this ? and i salvaged them.

Ectoplasm or Frozen Ectoplasm? (Might be a dumb question, considering I don't know if the frozen ones can even be salvaged...)

Glob of Ectoplasm XD

Aw, that sucks.

On the other hand, "some ectos"? I don't think I've ever gotten a single ecto by doing the Wintersday quests.
I guess Karma was evening things out for ya.

I tried WTSing Medals of Honor in Kamadan last night.

...

I was tired.

Not buying island guardian when they were 125e each

I honestly didn't know it was possible to salvage a crafting material. What on tyria would it salvage into?

Most likely dust.

this

or when kanaxai was stack or two

As far as I know you can salvage every rare crafting material into another material, some even salvage into other rares, for example Steel salvages into both Iron and Charcoal.

I logged in to GW last night hoping to see a Dervish update.

I decided to try and vanq varajar fells in the spur of the moment... only to find out that i was missing a necessary quest right at the end... i wasted 2 hours.

I got a q9 OS Strength Ornate Shield, I think it's stats were -2/45^stance. Sold on guru auctions for 15-20k some 15 months ago. Yeah. And I was even ~ happy about the deal at the time. I still want to kick myself sometimes for it.

Also, my first guru auctions purchase was a q9 Runic Blade which had a s/b of 20k and a b/o of 40k. I pressed the b/o button, thinking I would pay the 20k and get it right away. I really wonder sometimes at the process of thought that lead to that conclusion, seeing as I did that right after I read the rules and found out what b/o meant. I guess I was just nervous. However, I honored the deal, no reason other people should suffer for my stupidity. And I hate people who back down after a deal is closed.

Reminds me of the time when my alliance went to vanquish Sacnoth Valley....got through it all up to part where only the Charr fort was left and our dervish revealed he hadn't done Assault, so we couldn't get in...

As for myself, probably going through 3 stacks of fireworks to make space in storage a couple of days before the Party Animal title was introduced. I had three ToPK greens in the same tab which I should have just merched instead.

I done this i was letting around 3 stacks also off in our gh during a big guild celebration to find out about 2months later they added the party titles etc

1) Was in RA playing with one of those annoying Necro life transfer/siphon builds. Team was rocking, but for some reason, they had one necro/ranger left standing that all four of us just couldn't kill. Having never made a ranger, I was unfamiliar with his elite "Melandru's Resilience" and just kept spamming my blood curses. Ended up winning when the timer ran out, but wasted a good 7 minutes when I could've just wanded the dude. Lesson learned.

2) Just before HoM calculator, was doing some inventory cleaning and decided that since I didn't want to pursue the Black Moa Chick, so I wouldn't need this incubator kit thing. GONE. Was not happy several weeks later when I discovered why the incubator kit crafter would't talk to me. One per toon, + a decent chunk of dough in crafting materials. Dumb.

Went all the way to the end of the Cathedral of Flames, my least favorite dungeon, for a Z-Bounty and forgot to bring the sacred relic back. I had a full inventory and specifically remember thinking "what is this thing, it's not worth anything" and dropping it. The worst part of it is I've done Temple of the Damned several times, I just forgot that I needed the stupid quest item. The quest is still in my log, with everything crossed off except for "See Gron Fierceclaw" hahaha. I haven't had the heart to go back and do it again.

Dumbest thing?

On my first char, I was a W/E with like FireStorm on my skillbar and what not, even in RoF! hahaha

that was like 66months ago, but still! rofl (got the rof on my first char about 1 month into owning Gw...? approx)
