I really want C9 to do well this split!
My new underdog favorite is Echo Fox, though. After watching All-Stars this past year I really want to see Froggen succeed. A bunch of their games were long and exciting to watch and you could tell they were giving their everything after their visa issues were resolved mid-split.
It will be interesting to see how the mid lane changes (Sol, Taliyah, MYMU, mage itemization) and the neutral monster changes (herald, dragon, buff timers, etc.) will affect teams' strengths and weaknesses.
The roster changes make it feel like a whole new split too. We have Meteos, Impact, and Bunny starting on C9. Dardoch may be suspended from TL and transferred. Biofrost replaced YellowStar on TSM. NRG replaced everyone but GBM. Apex, nV, and Phoenix1 are new rosters to the LCS. There are just so many variables that are different from last split.
The EU LCS rosters will be pretty different too (if anyone is interested here). G2 grabbed Zven and Mithy. H2K grabbed Freeze from Renegades. Forgiven is on Origen with Hybrid. Giants is almost a completely new roster. Yellowstar is back on Fnatic. Roccat signed Steelback. Schalke is a new team who signed Fox. UoL has an updated roster.
I AM PUMPED
