I don't think they intended make spin track, SL doesn't have great spinners since Murali retired. Mendis and Akila relies more on variations than spin. I think it's ok to have a bowler friendly pitch, makes things interesting. It's a bit boring if the bat dominates the game. It's not like it was an impossible pitch to bat on, Samuels showed how, be patient and get used to the pitch and you can capitalize. Out of top ten wicket takers in the tournament 5 were spinners and the other 5 fast bowlers. So can't say that's unfair. Each cricket playing nation have a unique pitch profile, for example Ausie wickets will always be green and pace friendly, Indian tracks will be flat and batting friendly, etc. I think that just give cricket it's character and uniqueness that other sports can't claim.
