Antagon, this is very greedy of you. Just because fire has problems with shriekers, you want it nerfed. Air can take out shriekers, aether can take out shriekers. You're not going to be able to take out everything. Let's not forget fire has deflag, other elements don't have a way to take out such things. (Grav/earth and Entropy being the only other ones aside from mutations.) Should every element get their version of a deflag? What about a growth creature for aether?
Also, 2 RoF and 14 quanta can take out an entire field of shriekers. Other elements don't have the option of taking everything out. (Air does, but it isn't easy.)
