If there is one thing Riot is getting good at, it would be creating new skins that appeal to the community. Riot did an excellent job creating the Epic Winz Brolaf skin. Not only would this skin appeal to thousands of players out there that just want to be bros, Brolaf is a sure-fire cash magnet, netting $20 (or more!) from each sale.
Brolaf is an excellent follow-up to the just as crazy release of the Corporate Mundo skin. Riot does pay attention to the forums and know what the community wants. When the one word (spam) reply, "mundo", is commonly used in threads, Riot responded by releasing the legendary Corporate Mundo skin; now, when the term "bro" is used commonly, Riot releases Brolaf. Perhaps Trundle the troll is going to be released due to the increase amount of "trolls" on the forum? We can only guess whats next.
