The Siege maps for Paragon Cups would need 5 poles indeed.
Also there are currently only 3v3 Siege Cups, so make sure your map is made for 3v3. ;)
Further more I would suggest asking a Admin of the 3v3 Siege server to upload your map there, let it play and see if it gets a good karma. It would be good if a map is proven good by the community before we add it to the cups. ;)

Hi everyone. I'm a new mapper for Siege and Elite titles. Im hoping if you guys could test and review my map for adding it in the list of maps that would be played on in the Paragon Cups. I hope you guys would like my map. But it's a 4 pole map only. So I don't know if it is eligible for it or not.

I hope this URL works. Seeing forward to my map's approval. If their are any changes that are to be made - especially if it is to be made a 5 pole map - please do tell me.
