Actually, not true. I just tested this out with an alliance member who has updated, and our training times DID get a lot worse, but we're still way better off than any other nation. For a healer, it should take 15 minutes. If you are a non-french player, it will take just over 5 minutes with TB. If you are french, and you start one without TB, it will take 12 minutes (20% faster). Then, if you use your TB, it will now take about 2 minutes, 5 seconds, which is 14% of 15 minutes, indicating we are still getting 66% + 20% = 86% faster training.
So, going from French + TB to non-French + TB, you are looking at an increase of 240% in training time. I'd say that's still absurdly good, you?
