So what you are saying is they should make the game so even a chimp could pick it up and manage to get easy kills at any range using any weapon, that the game should toss its identity in the bin because people are too lazy to learn game mechanics, that modern gamers don't want to have to think about situations, they just want to see flashy numbers and get a well done sticker for turning up?
I'm sure there are players new to the series that are willing to adapt, to learn mechanics and try to improve without getting frustrated and quitting because it doesn't play like all the other generic shooters out there.
