The GMs that I associate with have been at the top of their game
No complaints about their job this past month from me. Going on them alone, I'd give the company 4-5.
Bringing the vote down - the website seems to have been experiencing some bumps, glitches, and snags (more frequently than usual). While this may or may not be in your control, I think better server stability should be something that the company strives for. Also, I don't mean to be harsh, but I think the web team needs quite a bit of improvement in their work.
3 - Shaiya GMs are doing a fantastic job, but I would like to see more server and website quality.
EDIT: Fix the exploit. You know which one I mean D:
