Personally yea most servers are leached to some extent but almost all servers have at-least 1 unique thing about it
-alison317 a 317 based server with a custom vote system that gave you 10m and a special ticket which you could use the kill extremely powerful monsters and get rare items like primal and not many servers alone have primal armor incorporated into them
-Rune-Warp one of the first of the few servers to have chaotic's dragon claws and custom weapons like the anger weapons put into it
the point is some servers are original's with original idea's but even original servers take something from a other server? atleast once in the time the server is up
I support slayer its very hard to earn points plus it would add a very nice method of making cash too.
