Is it advisable to sell my expensive players towards the end of the season ? So that I can get better players at the next level ?
depends on auction activity. if you have an active server, it is best to sell your players on the first few days of the season. you can get more money doing that. but you need to know the best time to sell. in my server, i get good price if i sell my players just before i sleep, which is about 11pm.
if you want to save tokens, it is good if you can hold on to your players for a few seasons. but if token is no issue, just wait for the start of the new season. if your server is not active, then try to sell the players toward the end of the season. take note that since your player will add 1 more year in age, the players lose 20% of market value at the start of the new season.
Now i have rest players that are not gaining much progress and continue to power train the others that are still having good skill progress.
I wouldn't recommend any power training until you reach about Level 10. You will be playing a lot of inactives over the next few levels, you will win easy leagues and easy champions leagues but you will soon find it boring and a waste of time power training when there is a lack of competition in the lower levels.
Also I wouldn't recommend training players to play in a new position because that effectively costs you just over 3 quality worth of skill points just to add a new position.
