Madfury skipped school lessons when they learned %. So it is useless to explain )))
What is french nation power? 20% faster troop builds. Blessings should not matter. It should be as it is written. If british tank builds for 60 seconds on training blessing, french should be built in 60 - 20% = 48 seconds, not 10.
When its 10 seconds, it is like 85% faster army build, so it increases original power 4,5 times. Not saying that it saves TB for more battles.
Than there should be a blessing increasing british loot 4,5 times, rome army buff 4,5 times up to 180, japanese PT buff 4,5 times right?
Other nations just can't catch up with that because this buff is better than all of their powers combined. That's why certain nerf is right, but fair % should be increased to 30.
