I think a poll should be made, stating the forums opinion with whether or not the majority wishes that it be implemented or not.

I myself would love mounts. Maybe more than two could be added, like a horse, a dragon, a yeti, etc.

Some could be purchased via platinum and others could be farmed. When you are using your mount, you run 10% (more or less) faster while in towne and PvE. This effect would of course not be added into PvP, because it would give an unfair advantage.

I think it would be a success because it adds customization. Plus for the buyer and STS.
