Hey, if anyone is looking for an easier path to the critical hit feat the composition I used was Hux capital ship starting with Tie Silencer, Command Shuttle and Echelon to start with both FO tie fighters in reserves, Plo Koon, and any random LS ship with high crit chance.
Once the DoT’s start stacking up make sure to bring Plo out ASAP to cleanse your team and keep the crits rolling.
I finally did it with Executor. I didn't use the ultimate or boba's super-bomb. This way the battle lasted long enough. If only we had a counter for these feats...

Executor - HT, Razor, Xanadu
Reinforcements - Slave One + 3 of Required faction
I used the same, but the enemy fleet dies before I can get the required number of critical hits. Crit feats always give me problems.
I didn't have any problems, but have heard others that did.
Other options for Crits are Rebels or First Order.
