Hi, everyone I'm new to the forums wave , please treat me kindly

As we all know ,each dragon(sabre,mountain,zephyr)has different
attack damage and overheat rate,but I don't know if it's at the same ratio . In short ,I mean ,do all of them deal the same damage per heat generated ?

The reason I ask this is because I enjoy playing as a dragon very much and I feel that the Mountain dragon has a lower damage per heat than the sabre and zephyr dragon(It's just my feeling, I don't know the fact )

So , can anyone clarify this for me? thanks in advance thankyou

P.S. Sorry for my bad English
