When u're selecting ur player's class highlight it with ur mouse and sum information about the player will appear just right of the names of the class. That information will contain sumthing called transform powerlevel. Reach this level, press Z and u will transform. For example: Gohan's transform powerlevel is 1.000.000 so if u're playing as him u have to reach 1.000.000 powerlevel and then press Z. Note: This will take a while and the higher ur powerlevel is the shorter the transformation will take. If it continues to grow it will reach a point where the transformation is instant, meaning u don't have to wait.This is called "Perfect transform powerlevel". Many people mistake this for the transform powerlevel for the 2nd transformation but it's not it. And as for the beam problem, it's easy: First of all, make sure ur ki bar is full. Then charge ur beam to max. and fire it at ur opponent's beam and hold LMB(Left Mouse Button) the whole time. Then turn on Turbo and turn off flying to preserve ki. This also depends on the powerlevel of the enemy. If it's higher than ur's than he has a better chance of success if he is using a beam of similar strength to ur beam. Hope this helps.
