First of all, whose to decide what maps are the best?
I like all the maps the devs map, some are worse than others, but hey, show some appreciation of all the their effort and time into it.
Of course there are maps that some players hate, but that is just a few, maybe others will join instead and like the map better than them.
For an example (like LuckOne said), Sidi Rezegh is a very well done map, others will take the devs work for granted and call it crap, I disagree, I like the map.
Another example, Operation Supercharge, this map is better played when 70+ players, less than that - it gets very boring to be honest.
As far as I'm concerned if we play the "best of the best", many will get tired of the same maps because they play over and over again. Variety of maps is essential for many players when 762 is basically the only server that is bracing FH2, and also WaW has done a great job on playing maps for Thursdays and Fridays.
People have different opinions toward maps and we should respect that.
