1. I disagree. I only train down to ~79% as this always keeps you training at a green level which is over 80-100%. Lower risk of injuries, so they say. Plus it gives you 12 hours before you rise back up to 99%. If I only have one game, then I train right after the game so everyone is just below 80% and come back in 12 hours to train further. You always want to keep them at a level where they will have the perfect amount of time to get back to 99% condition with natural rest.
2. this is the first season where I cared about morale. I have not noticed any difference as I am winning with or without it.
3. If you have a team that is better than most others in your league, why not attack? I am almost always attacking as that is the style I play. I play to score goals and get possession. If your opponent is much better than you, he will attack you, so you attack him and catch him on the counter attack. It all depends on your opponent, both home and away.
4. Apparently, bots play the formation that was last used by the manager while they were not bots. I have not seen any change their formation while they are bots. Thankfully.
