Laziness and the lack of skill among users are also contributing factors. As is the fact that the developers of TE and WOT have never taken this factor seriously.
Lider1 may have written it a bit harshly, but he is right in many ways. With the advent of HD, the main advantages of WOT, such as quick buttons for transferring armies/artifacts and the chess timer, have become irrelevant. All that remains are GM adjustments, one-sided games, and the mirror match. If you add this to HD as well, then WOT can only be used for flipping a coin (which, by the way, could also be added to HD).
