Does trainning make a hero stronger or it just help to earn 1 skill point? This trainning thing is take too much time and some time I can only play few minutes a day because some of my heroes is on trainning.
use the headhunter and special events to earn time sand and hourglasses. Then when your training times get really long (the go into the full-day range) you can speed them up.
From what I've seen your whole party gets stronger when your party level gets to a multiple of 5. This means buying a new hero can bump everyone's stats. Training itself just gives skill points.
Do everything you can to max out your skill points! I mean topping off every skill isn't essential but you will want a lot more than 1/level.
No train and push forward in fight areas to open up better loot. Upgrade that but not too much as it will be obsolete when you open the next tier of gear
