It can be a bit more official than qlranks, as only tracks the games you want to be tracked.
Not sure if skill matching gonna be implemented, currently its non-existant (?), or at least not in place at the expense of waiting time.

I think it can attract new players, actually it does already (i played a guy who just asked if theres an 50 frag limit in duel oO).

It pairs you with an opponent, offers 2 maps to vote from the mappool, if its 1-1 the system choose one randomly. Currently the only thing what i dont like its if you have ESL premium it counts your vote as 2, but not a big deal tho. Its kind of like a duel pickup with a ladder.

give it a spin if you want
