Marketplace suggestion: new feature.

Feature name: Increase reputation with <name> faction.
Information: It should let you pay coins and/or points for an increase of a faction's reputation.
Reason for suggestion: I think this would be a feature you could put into the Marketplace as I think people would pay for it. Older factions, less coins; newer and most needed ones (for enchants, etc), more coins.

PD: I refer to this as "feature" since "item" would not be accurate.

What is your opinion about it?

easier to be added into marketplace as a 'rep giving item' I think

You can buy full gear.
You can buy reputations.
You can buy mounts.
Why you even log ingame?
Next step is to legalize wintrading by buy arena rating direct from vendor..

I was mainly referring to Lordaeron as Icecrown is already a PayToWin if you have the money.

The items idea is nice.
