[Question] Why hire? Let the community help you.
Reading through [Retrospective 2015. Prospective 2016] thread. It seems obvious you are putting a lot of staff and resources into Lordareon. I have read in the Warsong Sub Forum that Cataclysm will receive it's updates when Lordareon has reach the expectations.
Why do you need to hire Developers, when there's developers willing to participate into the progress of their beloved realms for free.
You don't need to lend your core to the Developers (Free ones) of course. All the cores' run the same structure (TrinityCore) and isn't hard to replicate code from one core to another.
Bug Tracker.
You created a well thought Bug Tracker system. But it's missing one thing; An option to let the community help fix the exploit/bug.
TLDR; Instead being closed in and don't accept the advice and fixes from the community, allow the community to help fix the bugs/exploits, we are a community overall.
