What I did state was that games that are treated as battles, with more realistic types of armies ( as opposed to the SPAM armies, from any of the TW games ) are far more enjoyable
Then as I said, your problem doesn't have to do with the actual game itself, but with your concept of realistic armies and spamming. Therefore you wouldn't be against rules (or even mods) that promote those armies, not? I assume that many tourney rulesets have diversified the game, but I don't play RTW since I last tried 1.2 so...
Else the question would be about the mechanics and the engine, and you'd have to blame CA ;)
Naturally there could be a combination of both. But if it's solely about immersion, then you just can't force everyone to play the same. In the end though, tactics -and balanced armies- depend on the R/P/S system effectiveness.
