If anything, they need to at least add a new area for PvMP. Or maybe make a PvMP Skirmish system, where Creeps can create their own evil soldier to fight against Freeps, so that they can get rewards for their Creeps or something. *shrug* It would be fun if Creeps could somehow go beyond the Moors (it'd be fun to invade the Shire >:D) but... PvMP should sort of stay its own thing that's set apart from the rest of the game imo. Maybe create PvMP instanced areas (like Bree, the Shire, etc.) where the Creeps can go to if they control the Moors and the Freeps can hop in to try and drive them out or something? *shrug*

Mounted combat would definitely be an awesome feature in the game, but it'd probably be weird to implement. It'd be cool if they managed to make it to where it basically felt like playing your character on foot, but... you're not on foot, and maybe make it to where the horse/mount is sort of like its own entity, so... if the horse gets severely wounded, you'd be knocked off of it and have to either heal it or let it succumb to its wounds (thus not being able to use it for maybe 10 minutes or something). Hopefully they'll do something cool, because an expansion with Rohan definitely would feel odd if... everyone but the players can fight on their mounts lore-wise and whatnot.

What'd be awesome is if they added in such a system, and then gave Creeps the ability (though... Wargs and the Spiders wouldn't be able to work it out, unless the Wargs and Spiders (it could work maybe >.>) served as mounts (that'd actually be kind of cool to have a double-team thing) or something), so there could be some fun mounted combat battles in PvMP, where mounts would come into the mix of what to try and kill first - either the players themselves, or the mounts that are making them move much faster.

Also it'd be neat if they added in some more hobbies soon... maybe an Painter hobby (since I'd assume there was some type of on-paper-art in Tolkien's universe) where you could create paintings and use them as house decorations/share them with others? /shrug

Anyway, off to go get in some play time with that 25% extra exp >:)
