There are 2 panthers spawning in the German main base. In case they are destroyed you need to wait 45 seconds for a new one
well I dind't know that, excuse me. anyway from what I have seen panthers never dominated the battles. perhaps it belongs to the rather unexperienced players ...
but in general, open maps are more welcome to the players I guess. meuse river, totalize and now arad offer even conditions for both teams so I think this should be marked, even if "historically correct maps" with push code etc. are there. those maps are fine too, usually not playable with each number of players on the server. if there are not enough players, you get bored 'cause nothing to do, if the server is maxed out those maps are crowded too much.
opened maps are ususally free of those "problems" since the players have more control, more options to do on the map causing in a more fluidly gameplay. at least amo. in general a mixture of those types of maps is ideal.
