They have devs that can do what ever their imagination can conceive. iRO has to go to daddy and ask to fix his stuff.
Maybe iRO should start using the open source server...
The popularity of pservers has nothing to do with the security of iro, though, as their tools are for breaking into eathena, not the official servers.
You can bot and autopot eathena the same as iRO, but that is a client side issue, and you can't solve that problem with software. But on the open source server, for example, they can fix the gutter line bug, and duping is a problem that can be and has been solved. How do I spell it out? The software is just better.
