I have not tried these combinations since the last FAQ which changed TLT into a single attack that happens twice.

Is Bossk now similar to cluster missiles and munitions failsafe that both attacks would have to miss before Bossk would trigger? Does he still trigger as he always did, TLT1 missed Bossk actives, if TLT2 misses he would activate again. I understand forecontrol system was changed with TLT and they have similar wording.

Would Greedo activate on the TLT1 or on TLT2 if TLT1 hit a shield or missed? Is it restricted to TLT1 only?

TLT is not considered a single attack.

TLT is 2 separate attacks. It's just that you don't trigger any "after attacking/defending" effects after the first attack.

That should answer your questions:

• Bossk only triggers after 2nd attack, if both attacks missed
• Greedo only applied to the first time you attack - so only the first of TLT's 2 attacks

You should really go look at the timing chart in the FAQ. It might answer a lot of your questions.
