There are much simpler ways (and much more effective too) to improve the game than building a new game. Even the first point shows how unrealistic the suggestion is.
Removing instances implies going to a server-oriented game (Instead of P2P), meaning either losing money or requiring a monthly fee. Making such a change after the release is pretty much impossible.
The rest of the suggestions is a lot in the same line, changing the game mechanics completely rather than complementing what exists already. Very irrealistic.
There are still a few good ideas.
