Hey man, great idea there. You make a concept similar to compendium lol. There is compendium in dota especially when there are TI draw near. Maybe i suggest to widen your concept and web design? Maybe that can help.
I really like idea with compendium in Dota. It can be very profitable. As for me, every compendium so far was in plus. So I can spend this money to buy some other games.
