Just let me be clear to begin that i was so excited for when the maps came out i thought they were good but noticed a lot of issues. Lets start with stadium.
Stadium is a well designed map although i have reason to believe that they rushed the making of the map because for some god damn reason treyarch thought it would be a good idea to spawn guys behind the other team every time than they spawn them away from the other team or in my case the headquarters cause i play lots of hardcore headquarters i know this issue came up when the game was released and they have tweaked it a bit but it still isn't good. As for the so called "Run and Gun" style they originally gave it why in gods name would they put some much hiding spots for people to camp its a stadium a stadium doesn't have its own little garden it should've been more of a parking lot on the outside instead of rows of buildings and walls and dark corners now i understand there are ways to beat the campers but this is not a "run and Gun'" map whatsoever in my view its a larger version of lets say firing range with a stadium lobby thrown in.
Now Kowloon, Personally my favorite as i have only played three of the four maps so far i havent really noticed a lot wrong with it although the rain is annoying as hell as it ruins basically all the footsteps. Love the Zip line aspect to the game but it is a decent size map and with all the buildings i definately recommend either marathon or lightweight but not both no need for that amount of running. I also think that Tactical insertions are better than claymores on this map because of how complex the layout is and how many good spots there are to put them without getting noticed right away.
Discovery was suppose to be one of the larger maps with great site lines for snipers and coming from someone who likes to snipe a lot i fail to see these great sitelines they have been talking about i found maybe at the best one or two good spots but for a big map like that holy crap get rid of some of the mansion buildings that are in the way like there is no need for a giant building every 50 feet that ruins the map as a sniper map i have a better time sniping long distance on firing range than on Discovery i like the layout but to many buildings and not enough site lines for sniping.
Last but not least you would think that the new maps would be popping up so more in the rotation but when they mean a little more priority they must me the size of JD 2020's dick which is almost invisible because he has no balls to say anything on this site anymore i mean seriously i dont want to play 6 old maps before 1 new map not very fun.
Anyways there is my 2 cents comment below let me know what you think
