There are two kinds of players who play at 2.0.
There are those that pretty much always played at 2.0, they have become competent at the game playing at 2.0, and now cant stand to play at 1.0 simply because to them its like wading through molasses on a cold rainy day. These players never learned the details that can go into creating better economies, better armies, better strategy, etc. These players, while capable of defeating many 1.0 players by being used to the speed, are crushed patheticily by the 2nd set of 2.0 players.
These are the players that spent a long time playing at a slower speed, they learned the details of the game, they learned them so well, that when making the transistion to 2.0 they do not lose much in game play, they are very fast themselves and a game between this kind of 2.0 player and the other kind is much like an expert slaughtering a newbie.
I know its somewhat unfair, odviously I havnt played all 2.0 all the time/only players, but, Ive played enough and ive yet to see anything close to an exception.
I can play at 2.0, I even enjoy it, it is a great, fun challange, sometimes, I wouldnt play it all the time, nor even very often, but now and then it can spice up the game.
In fact, id rather play at 2.0 then 1.5, as 1.5 messes me up, I attempt to do more then I am capable, trying to play like I would at 1.0, but at 2.0, I am fine, I can let go of some details and concentrate on winning the speed game. And it is still a fun challanging game with tactics and strategy, just of a lesser form in detail, but no less in grand scale. Pulling of something that at 1.0 would seem normal at 2.0 is a great achievement. Dont think its without a challange, the 2.0 are right in that, and its not sheer speed, I still wall at 1.0, hell I still wall my opponents in at 2.0
But, a 2.0 only player will get massacred by a 1.0 player who has learned to adapt to 2.0.
