6)I guess they're still helpful, only the clicked one gives you 150% bonus for 20 minutes or so. At least that's what the game says.
That's what I 'm asking. Bonus gives motivation or also efficiency ?

2) Attack or defense bonus always working in a game ? What's the difference from setting Hard Attack or hard Deffense ?
- Yes because that's how the game is designed but how much this difference will count I guess not even the developers can't give an directly answer who will please everyone. In big lines is same with hard attacking and hard defensing, is motivating more the players.

Scenario :
I 'm playing a game, setting defense and only my attack bonus left. What it will be ? My team will performing like wants to attack ? What is this use of this bonus ? What is the effect if not watching and having defense and attack bonus ? What if we 're playing defense and we use the attack bonus ? Why after every game, I cannot see any difference in condition loss if condition bonus is activate anyway ? Condition bonus of 10% affects more than 2% or it's just the 5 times we can use by clicking (2-4-6-8-10%) the bonus ?

7)
But there seems to be no difference between very easy drills L1 and L2. I have warm up L2 but still +1 per each player.
I 'm talking about lv difference in same drills. For example World class Sprint gives better result in the gaining of a player than a lv2 Sprint ?
