Guild Wars 2

Hey there. I’m always frustrated at ArenaNet for them leaving too many details up for interpretation within the achievement menus. Yes, I did read the forum post, but that only points in the general direction of where to start. I’m not the only one, because when asking these questions, not many people know the answer in map chat.
Saving all my hate speech against ArenaNet’s awful presentation techniques, I have some basic questions that I would be greatly appreciated if someone answered:

- Champion of ______ (Variant for each area) achievement.
"Escort (Norn/Human/Etc.) emissaries to hot-balloons" and then gives a kill count. Already this is confusing enough, but to the question! Do these kills need to be obtained during the escort missions only (if so, that is absurd) or is the title misleading and the kills can be recorded during other balloon-related events?

- Balloon Tower Tourist achievement.
I love this achievement, but it’s either broken for me or there’s a special requirement. Sometimes when walking up to new towers, the chest will already be open and the achievement does not register whenever I ride the balloon to D’s Reach. What are you supposed to get the achievement to registrar?

- Champion of _____ (Crown/Black Citadel/etc.) achievement.
This one really confuses me. I think I’m expecting too much from Guild Wars 2. So I understand that the Pavilion is basically a farmhouse for champion loot. The achievement says to get kills while representing that faction, but there’s not enough achievements to the available factions you can represent while you sit at your computer for three hours getting these 400 something total kills. Is this meant to be? So I can get my kills for the Crown and Black Citadel and not even worry about representing Kryta and other non-specified-in-the-achievement factions?
