I think the rules should allow players set up positions of major pieces freely. Let players find out best setup for each army. 
Tutti-Frutti has a ABC combination of rook bishop and knight, which is much too powerful. Armies in ABC chess are less powerful than that of tutti-frutti, which is better for cwda design. Players can define more armies with balanced power for ABC chess.

The 'drowning rule' means that you can't use pawns to support cross-river attack. So just wait your enemy come from the other side of the river!
Another river rule in Catapults of Troy is also interesting. But these rules all make games more drawish, because they weaken two many pieces. I think a river rule should strengthen more pieces than weaken, or at least just weaken a few pieces like in Xiangqi.

There is a question about the two essential elements of chess variants. 
In some chekers variants a cheker can promote into a king, then we get pieces with different powers. This is one of two most widespread and important similarities. But chekers is still not some chess variant. We can even desighn a chekers variants with king in initial setup. Is this a chess variant?
Is the breakthrough game Camelot a chessvariant? It has pieces with different powers.
An elimination game with pieces of all pawns (or rooks, or queens) and a chess board is also called a chess variant. The reason is probably that pawn is derived from chess.
Once again, are these two most widespread and important similarities essential to chess variants?

The rules on this page

say that the queen in shatar is the same as FIDE chess. Which is right?

Interesting rules about leaving Rocks ,  leaving Vectors and movements of V and A . Movements and captures would become unpredictable as many Rocks and Vectors as there would be on the board . But how Cannons capture Rocks is not so clear according to the above .

A King is severely threatened by the opponent Queen's Guarding which would checkmate with the line half-open and unprotected . I don't know whether players would be encouraged to attack with Guarding or discouraged to defend opponent Guarding . They may also reserve Guarding for a fatal strike preventing from early and easy moving of Queen . 

PS : I haven't played this variant for more than two years , which is not good of a CV inventor .

It seems to share some common features with shogi.

Recently a zillions implementation of Luzhanqi has been published on the zillions website. The AI can see all your pieces.

By intuition, the promotion of soldier can affect the strategies of the game drastically. Soldiers would not be sacrificed easily, and exchange of chariots or horses would be played more positively.

Also by intuition, I think the move order gives too much advantage to Chu (the green or blue) who make her setup according to Han's setup and move first.
