You will be able to buy it when you either "level up" or WGT rethinks its policy regarding "tier based equipment'.
The WGT eliminated of the "tier based" system for the purchase of equipment in favor of a "level of experience" based system...fact is they should have simply added the "level of experience" system as a second pathway to the better equipment...too bad they did not embrace the dual pathway suggestion...now they will either have to backtrack or folks in your situation will remain quite frustrated...Harve
