Yes, but that doesn't show they are less skilled, nor does this effect required them to be less skilled. If you suddenly increase the difficulty, success rate will be lower, no matter the skill level. It would have been similar 2 or 5 years ago.
No not at all, skilled players hit what they are aiming for FAR more often than a less skilled player. The size of the town wouldn't have mattered much to skilled players. Todays players count on numbers to make the hits. If you throw 60 1000lbs bombs at a town a few building are going to fall, but will it be enough? Skilled players could do 5 towns with that and still have people holding bombs looking for targets.
Todays players jump right into a new game. They don't look at manuals, they don't read instructions. If they get stumped you hear it on the radio "How do I make my tank go?"
They don't take the TIME to learn. When they play, they team up with others of their ilk and all they get is the very basics of game play, because after all those "teaching" them don't have the TIME to teach them, nor do they nor much more either. I am NOT talking about the Training staff. They do an awesome job with THOSE THAT ASK for the help. Those players are the ones I look forward to meeting either to fight WITH, or AGAINST as they seem to want to learn the game and how to play it. The rest just want to WIN THE GAME, and today is far better than tomorrow.
