I agree, endril, that the French glitch should be fixed, even though I'm french and really prefer to train quickly. It just doesn't make sense, and it's too much of an advantage. Having said that, though, maybe if the glitch is to be fixed, the 20% should be increased to 30% or 33%. This is the primary advantage of the French, and I'm not sure that a 20% reduction in training time is the equivalent of the larger roman army, British archer range, or the 40% damage bonus to Korean archers.
I do have an alternative, though, to pushing for restoring the tb to what it was. I'd suggest faster training across the board (outside of the tb, that is). This would make the game more fun at early and mid stages, and therefore help the game to retain more players. Keep in mind that many people aren't even aware that the tb exists, and we all know how much of a game changer it is.
