on bc2 i could rack up 30-40 kills on one map fairly regularly on bf3 important lucky to get 15+...the game is not as action packed for sure.
Play 64 conquest metro on hardcore, very easy rack up mammoth scores. For me battlefield should have more tactical moments, I don't need every map to be a COD meat grinder affair. Maps like mastuur city, dragon valley and kubra dam are badly missed in BF3 and that's why players are bored of all the current BF3 maps all ready, there is no depth to them.
