Hi, the loggin capability always face with all people. However, it is not logically and unsolving any problem. You can ask me WHY? There are many reasons about that. In my opinion:
1/ someone said it discourage for donated work. So what different between donate and pay to play? Be fair with everyone, not only individual facing this issues. Additionally, donated membership got many benefits already such as mount, extra exp and money, rare pokemon, special access to areas, cloth and so on. What u want only got more benefits for individual rather than everyone. Fair for everyone guy. I means donate having distinguish meaning with pay to play. No offense with this agure.
2/ How about priority loggin for membership. Well, how u know the current donated player less than 1800 cap on server? The point is when having priority loggin for membership, how u sure u can get queue? The sub-effect is forced every one to "donate", so when it happened @@ what priority work? Nothing, and then nothing sloving to problem.
3/ it still are beta, so I also don't know what will be implemented. Maybe the alternatively solution is new server for only membership, however the reason 2 =,= poor. Maybe stability > more cap, and then cap will increase after.
P/s: maybe reason for still not popular is in development process (beta), the limit server, however, i think we will love for quality rather than quantity, right?
