Dungeons and Merchants
Yes, I very much agree. I ended up with the permanent TP item and thought I could be a full service mesmer (sorry, no happy ending!), but it’s the same way. I can sort of see the reasoning for the TP contract (the contract is with you, and delivers only to you), but the general store-style merchant I think should be open to all.
The biggest problem is more that the items are rare enough that you don’t see it often, so people get confused and think the NPC is broken. Though I do love putting the TP merch NPC in weird places (like on the EB jp pillar across the chasm), and it’s nice in WvW as if you die you can still spawn it (I hope they don’t nerf that) and people will come to the TP icon on the map and you get a res when they come to check it out. It’s also fun to taunt those who slayed you with a TP they can’t use.
