What is the biggest meta challenge with 4 rebels? Is it Uboats? Or is it imp aces? I think 4 ship rebs can match well vs one or the other.
In my opinion the greatest challenge is matchuping up well vs both dominant archetypes. That is; ability to have a solid game vs either archetype.
Biggs is a thing. He works now, maybe better than ever, paired with a DTF buddy.
Rebels have a ton of moving parts that individually trouble the dominant archetypes. Stress bot, Biggs, Wes, and access to cheap guidance chips abuse.
I think most optimal 4 ship rebels need to plan on removing a Scout before it fires one torp. The Uboat game is vastly different when they start firing with only 2 scouts.
Rebel anti ace tech and pieces are fairly modular, with typically unfortunate points costs. Poe does good work vs aces. Stress bot is obviously bad news. Blockers ruin aces.
2 Talas with missiles and chimps sets you back 34(36) points. Two missiles at PS4 are very dangerous for PS3 Scouts, most of all against scouts without overclocked. Biggs protects low(ish) PS missile caddies from aces. Missile caddies claim table pretty well vs aces. PS4 green squads with homings, crack, adapt, and chips are 25 point nightmare ordinance for aces and Jumps.
15 point prototypes are pretty darn amazing blockers.
These are some of the things I'm looking at.
What's holding Rebel 4 ship builds back? Is the ace match that hard? I tend to think we have yet to see ordinance fully realized on the rebel side of things. Removing a jump boat before it fires and threating aces with ordinance seems workable to me.
