I wonder how many ways that could be considered griefing... even if it's hilarious. Even just doing it to guild mates. Although paladins (and more) have already been offering rides in choppers and mammoths for a while and jumping cliffs. Or the recruit a friend rocket...
I'm pretty sure the post implied it'd be from an alchemy research, not an archeology research. Although drastically vague and unconfirmed on the main page.
Back to topic: Why would you want to nerf travel form and such? travel form is a great PvP tool to either get away or to chase down someone. Instant cast, in combat, and it break snares... oh and it will be usable in doors now as well. Flight form is great too, someone camping you means you can res and instantly fly away. Oh, and didn't you know you can use a 2 of 3 gathering professions in while in form? Makes it that much faster, and who knows about archaeology...
Sure the forms look a little out dated (at least for travel/aquatic) but the forms are very nice indeed. To ask for a nerf just to carry one is a bit much and to ask for buffs is ludicrous.
