Guild Wars 2

So, I’ve just got a question… I’m sure it’s been asked before, but searching these forums with the search function doesn’t even work it seems.
Anyways! How is it that when crafting the ascended materials such as Lump of Mithrillium or more specifically, Spool of Silk Weaving Thread, that the required materials for the silk version are twice the amount of any other?
Every other ascended material with a time gate on it costs 50 of it’s respective material, yet silk is twice the amount.
Where’s the justification in this?

Hello! I’m currently in search of a raiding guild. I main a Revenant and my gear consists of exotic/ascended. Trinkets are all ascended and chest piece. Working towards completing the set. I run a zerk/marauder build. Here’s a link to it.

I only lose out on 57 Power and 7% Crit Damage in exchange for a bit more hp when burst/accidental situations come into play. If this is unacceptable, I suppose I can go back to full zerker.
Hopefully I’m understanding the time right and your 9pm is 7am for me? I live in the Central time zone. I’m just curious if this time is concrete? I get done with work at 7am and get home by 7:20am. This would only apply to the Friday raid schedule.
Anyways, thank you for taking the time to read and consider my application!

Hello there, would definitely be interested in joining. I’m mostly a PvE player, but don’t mind some SPvP every now and again. Of course, I’d only consider myself average at that aspect.
I’ve been playing a while, but took a break for some time and have now come back with the addition of HoT.
I main a Revenant, but used to play Thief and Guardian.
I’m mostly looking for a guild that has strong ambitions to raid and hopefully get a set schedule going. Weekends work best in that regard, but I am available during the weekdays as well depending on the times.
Let me know and thanks for taking the time to consider this!

Yesterday I made a $10 purchase to acquire 800 gems in game.
Today, on 5/5/14, I took a look at my bank account and it’s saying I was charged twice for that one time payment.
I don’t even have the extra 800 gems that would of came with it; should of I accidentally bought them twice.
