So I have all 4 of the starting dragons you can find, and I am stumbled by should I evolve all 4 of them into the next 2 dragons and then evolve those to the Omega? I love my dragons and have them at level 99. It might be just me but it seems like a ‘waste’ to get rid of 4 dragons for 1? Or is Omega insanely good that it is a pretty much no brainer? Finding it hard to decide to lose these guys 
you get four more, then fuse those 
Get the omega. It’s worth it
Omega is a great pvp ark. He’s 12 stars, so he’s pretty strong. 4 99 dragons would be better for Pve, but you can farm some more as always
