Here's the thing... I like both teams...
IMT has has a big fan base who is crushed by this decision. the team has been nothing but successful since it's inception last year & has been the biggest new name in NA since C9 exploded onto the scene in 2013. Noah Winston is a pretty awesome owner & one of my favorite esports owners out there, he puts integrity over talent & still gets results (Just look at his decision on his counter strike team). IMT will be dearly missed...
But Echo Fox is one team I said HAD TO STAY... It's all about marketing & making money in business. And Riot is going to need their most profitable owners brand in the league, Rick Fox. When ever a non esports source writes an esports article, it's about this guy. He's a celebrity & attracts new clientele & sponsors that some of your more successful owners can't. When a source like Forbes writes about the profits of being an owner in esports, they're going to write about Rick, because people know him. Most people are unfamiliar with Regi, Jack, & Hotshot, so even though their teams are the most successful & popular within the community they aren't going to bring in new fans like Rick's team will. as far as how Echo Fox is a much worse team than Immortals, yes it sucks to lose immortals, but the players will find new teams. And besides I like Fox's players Looper is one of my favorite players ever (SSW was the best team to ever play), Akadian is a budding superstar, & Froggen is one of the OG superstars. They just need to fix their bot lane to be competitive.
