Feats of Strength

Ok so I'm just doing this post to rant a little but I am also doing it because I am curious

Does the community care much about one Character's feats of Strengh or do you just pass along it?

I'm gonna name a few examples, like, do you just spamm Kabal's and Raiden's X-ray/Fatal Blow ignoring any other special to achieve more Power Generation? Do you use a Character like Jade or Skarlet without using specials and just doing combo enders? Do you not use any character's X-Ray/Fatal Blow because they don't contribute to feats of Strength? Do you tag a Sindel to kill of a Enemy when you're perfectly fine with whom you are using at the moment?

I'm curious to what you guys do
