In EWR you have good and bad feuds i have took it upon myself to hand out a few good feuds and examples of bad feuds.

Good Feuds:
Eddie Guerrero vs Chris benoit
Edge vs Rhyno
Pogo The Clown vs Doink The Clown
Kurt Angle vs Chris Benoit

Bad Feuds:
Ultimo Dragon vs A-Train
Big Show vs Funaki
Kane vs Tommy Dreamer

The Key to a good feud is to document it well (e.g. finish it with a speical match and use interview etc.) (A bad feud can normally be a big guy (.g. Big Show vs a cruiserweight (Kidman) so try to use main eventers against main eventers etc. and a good heal vs face feud always brings in the ratings. If your gonna have a face vs face feud or heel vs heel try to turn one of the workers so it turns out better.
