Um, you really should link uss to the current existing versions of the map. Yes they may not be that good but its a start.
If you have not released a version of your arena yet, then why v3.56? I mean that version number makes no sense unless you have released one aleady.
Anything before the first release should be 0.blah or 1.blah or 1.0 alpha and not v3.56.
The first release of any map should be in the 1.blah number range. Only if major and total changes are made to the map should you move up a whole version, which can never occur before offical release.
Ofcourse I am probably being very stupid posting this as you probably know it, anyway it still would be good to see and be able to test your current release version (which I guess you have since you are on v3.56 already).
Have to admit that the arena background idea is totally unique, and I have to congratulate you for that. However next to that it sounds like any other arena with some AoS base elements. Terrain also looks a tad on the flat side, to get anywhere these days you need breathtaking 3D terrain with a lot of detail (See Diablo 3 or TKoK for examples of how modern WC3 terrain should look).
Also may I remind you about our multi post rules and bump rules. You may only bump every 48 hours and with reason.
