This is the second column from Massively OP on the issue of mounts and motion sickness.
"The roller beetle: Excellent mechanics, but watch for motion sickness"
"Sadly, I do have to point out that the speed, tricks, and airtime comes at a cost: I started to feel fairly heavy motion sickness after 5 or so minutes of rolling around on the beetle’s back. I do suffer from motion sickness quite easily, however, so I’m interested to see how the general feedback goes throughout the episode’s launch window. The first iteration of the raptor made me feel awful too and that was fixable, so I’m holding out hope that this mount can also eventually be enjoyed by those with delicate tummies like me. The development team admitted that the roller beetle was a massive design challenge: The experience would be dampened if tiny, normally inconsequential terrain details such as a little rock or lump slowed him, which was a huge undertaking to get right. I feel that the team did get the balance right on this one, which is a fantastic achievement."
My thread on the topic...
Info on motion sickness...
I know the team is dealing with server issues, but this is an extremely important topic that some in your player base would like to have addressed because of health concerns and enjoyment of the game.
Edit- I have not experienced motion sickness while gaming until GW2 mounts. And to give you a comparison of my tolerance level to movement in gaming...
