Although I do have a miner alt I stick to pond to avoid the hassle , however I've heard that some players mine with alts and then defend it with their main character. Perhaps a rule should be introduced to stop this. Seems unfair for main players characters trying to start their mining thinking they can attack a low levels mine who's taking up multiple spaces to then have a high level character jump in. If they wish to keep their mines they should put the effort in to make their alts strong, of course the main character could take the mine back after but at least this way things would be a bit more fair.
