I find personally the skilltree for the generals maybe a good Idea, but I believe it is not a good Idea to introduce.
For this I have several reasons:
1) Guides will be impossible, there a already existing general can have more then 1000 combinations
If you put this together with other generals then 1 guide now will then be 1.000.000 guides for all the combinations
2) Combat simulators are impossible, with all those combinations.
3) When players are mixing up the same type of gen with all kind combinations, then mistakes will be coming.
And with mistakes the losses of expensive troeps, with result with complaints and at the players which will drop off from the game.
It could be a good idea, when all the generals are the same, so there is 1 kind of general, and with this you could modify its skilles.
For this game its to much.
So please do not introduce the skilltree for generals. Its a bad Idea...
