Me too, i finished it easily way back mid-3.0 .. that's why i don't know the new changes happening in the Ultimate Training, tho my 2nd main account is not yet finished the trainings and i haven't played the UT in that account .. Maybe the reason why they changed the difficulty of the said trial is to keep players challenged and take time to finish the entire Ultimate Training because of the current status of the players who already finished it and requesting/demanding them to release the update for the UT .. And ofcourse, yes, i know most of the players will say that this is unfair and not good but we must understand also that the game is adjusting for us to keep and maintain the whole balance of the events and features of the game .. Just try to keep cool while playing and trying to finish the UT, patience is the key to success :p ..
