Summoners Do Too Much Hp Damage

I get doing damage with your summons, but I just took 27 damage with only 1 actual enemy unit standing 2 rounds after Dragon. That is way too much damage, yeah you want game to end faster, but losing that much health to the only person who can beat me and losing because of it is kind of ridiculous. There was only 1 unit left... I killed 8 of their 9 units, but died with almost 30 HP left. That is kind of unfair in my opinion.
