Speaking of Felicia, who are potentially her ideal teammates? Strider seems obvious,
which seems to suggest Felicia/Doom/Strider, but I'm not sure which kind of projectile assist the cat likes the best.
There are quite a few ideal teammates for Felicia. Generally I like to have a good horizontal assist and a good antiair assist.
Many horizontal assists work great, either fast ones like Hawkeye or Taskmasters Arrow assists, Doom's Plasma Beam, Arthur's Daggers, Unibeam.
Slower horizontal assists also work well, RR's Spitfire assist and Dr. Strange's Bolts have a gap between projectiles that you can fish for command grabs during.
For antiairs I usually just pick either Dante's Jam Session or run Strider with Vajra
Felicia/Hawkeye/Strider is my main team and it works quite well. Felicia can approach with ADK + Hawkeye assist and get a full combo off it if it hits, or continue pressure If blocked. Both characters get full combos off vajra assist. Plus I've got a Dark Anchor.
I think your idea of Felicia/Doom/Strider is also a very good team. I'd probably try it out if I ever learned how to use Doom.

This patch discussion in the FGW thread is giving me a headache. Why would you want to get rid of some characters loopable hypers? It's not even a problem, it requires burning lots meter and is usually pretty inefficient(meter wise). Who would want to nerf sentinel? It defies logic.
