If you need a vote, I'd go with the "remove collision" option.

I would however like to offer a few other ideas should the "keep it" option end up winning. It seems this suggestion came about regarding the congestion in cities.

1) Home Point INTO the Mog House. This is done in FFXIV when Returning to your Inn Room. It seems the biggest congestion is people warping home after an event and getting up to AFK. All those people are now in front of the Mog House. If we could Home Point directly into our own rooms, that could alleviate some congestion.

2) Make restricted items salable on the AH. It seems another reason for the congestion are people with AFK bazaars selling items that can't be listed on the Auction House.

3) Make a "Bank" of Vana'diel. I've touched upon this in another thread long ago, but basically it would be a sort of trading venue for various currencies. The main reason for this is simply because acquiring full stacks of currencies can take quite some time. The Bank would allow people to sell or buy what is available regardless of the number a person has to offer or want. This would work in conjuction with Point 2 above regarding AFK Bazaars.
