Does instant transportation effect game immersion?

i dont think it will be a serious threat to FFXIV though because there aren't -that- many people into it

Indeed, the differences between Warhammer 40k and FFXIV are huge and abundant. One is a violent sci-fi set in the future with spaceships and different planets, the other is a fantasy game with scorcery, swordfighting and kingdoms. All down to personal preference, but I imagine there's more FFXIV players that prefer it's fantasy genre over playing a sci-fi.

If you meant that there weren't too many people into Warhammer 40k though you'd be wrong. I go into a nearby Games Workshop quite regularly and it's always packed full of people, with new people coming in all the time. W40k - Dawn Of War really helped to promote it as a franchise as a lot more people started getting into the tabletop game after playing that, from my experience of talking to new tabletop players.
