A plea to CA

[orangat]

PLEASE please dont make units untrainable once you get past a certain year. In RTW and MTW it was really annoying. In RTW by the time you get marius reforms you arleady have 2-3 armys on the move, and all of them experianced, it stops your conquest for some years and complicates everything (once you conquer a city your depleted forces, even though they have 3 gold chevrons, you have to disband them).

And it makes no practical sense whatsoever.

Agreed.
Suddenly untrainable units is nonsense. Besides the obvious problem of having to train furiously, the player should have the option of retaining as many old units as wanted.

As long as the AI can adjust to changing technologies. If the AI from MTW only trained FMAA when it had CMAA available then that's bad. It should be up to the player to keep training old units but make sure the AI doesn't misuse this feature.
