Currently if you are a caster and u initiate your attack on a group of monsters by using a spell then your heroes will pretend nothing is happening even in attack mode, unless you space-bar mid casting or lock a hero on a foe to alert them to participate.
It would help if they interpreted your casting as a sign to commence action just like when you space-bar to use an attack skill. This would be especially helpful when you are holding an item and cannot, obviously, attack by clicking space-bar.
