I don't think it will be a BR era as MIBR is not improving and all the other teams are not top material imo. While Furia has done great recently, I doubt they can remain consistent and keep up the energy and momentum. They have a specific play style that has fucked teams up before, but now it will be harder for them to keep up as teams will find counters to their style. Also, they just lack pure experience which i think will be the deciding factor. I doubt any EU teams other than Na'Vi will be able to compete with Liquid so the next era, if we have one soon, will be Liquid.
