pff, I wonder why people still do this.
I assume, they do it because they don't know any better.
@odhlo2: Implementations of Tier 5 (before Yedang released it) have been among the highest modifications in pServers. They took the development teams months to implement fully, though several people have added the odd skill for one or two classes.
We have *some* information from them which a team of developers *could* work into a full working replication of the official Tier 5, given a few months concerted effort. They will now have the advantage of being able to use the design template from Yedang... Animations, stats and so on that others have had to make up for themselves.
Most importantly, this is not a task that a highly skilled developer with years of experience in reverse engineering PT and no other obligations on their time would want to take on on alone. Probably.
If they did, and achieved it without more than hints from others, that would be some pretty extreme dedication.
Feel free to take that as a challenge, or not.
