The house system is this game is pretty much a fail, I pm 3 people who own houses so I can try to buy from them, and those 3 persons was the same guy.
I was like wut?
Then I realized its not about money, its about free houses for everyone who has a lvl 50, which can be achievable quite easy.
There are some stuff that could be changed in this server but its not really up to me, just sharing my opinion.
Anyway yeah, nice to know there is probably people with more than 3 accoutns that own houses and all they need to do is login 1x per month to keep it.
