Guild Wars 2

Hello i want to start off saying i love the game and everything that anet has done thus far but there is one problem i encountered with the chest that tixx allows you to have. I was in the spvp map when i talked to tixx and didnt think any better of it when he asked if i wanted the gift, so of course i took it and got 2 spvp/wvw finishers and a pvp back-piece what im upset about is that it is a pvp back-piece and not one i could use for pve which is normally what i play. So im just posting here to see if i can get the attention of the mods or someone who can help me or tell me there is nothing that can be done to exchange the pvp back-piece. Hell take the stupid spvp finishers too i dont want those at all aslong as i have the pve back-piece. Anyway i guess im just alittle kitten that it didnt give any warning or anything that opening it in spvp would result in spvp items. If you think i am wrong im my thinking post telling me why and maybe it will make me feel better and be less annoyed
