I am a First Sergeant with Isada m0 Hunter m2 and Smoky m3. I was wondering if two ranks from now should I get Thunder m0 or Vicking m0 first , or should I upgrade Isada to m1 before i get either one? I know i shouldn't get Hunter m3 because for 100 crystals less I can get vicking m0 with 10 hp more. And im going to keep isada till i can get freeze wich is along ways away. Please help me out. Also I have 526 crystals now.
