Ok so none of you actually hit on the real game changer here. I will share this from what I heard while at a recent tournament where Norm was playing Yik, you might recognize those names from having WON the **** worlds and having placed quite high.
The real game changer is relay. Period.
Right from the horses mouth ok?
You have a pair of squadrons that are very hard to kill, that can be escorted by biggs and allow Yavaris' very powerful ability to have scary threat range AND leverage the transports ability to activate while remaining safe. Reeikan is just a super annoying insurance policy that allows the player to decide if he wants to play defensively or offensively. The amount of flexibility and survivability this combination provides is downright scary.
Yavaris + gallant haven + relay + Reeikan is currently OP. Everyone knows this.
Norm himself is an extremely good, meticulous, intelligent player and he primarily plays imperial but he literally could not find an imperial counter to this OP combo (from what I heard him say) edit: not one that would counter it and work vs other lists.
You want to nerf this combo without changing much all you have to do is make relay only work once per relay provider per turn. All of a sudden the fighter ball loses a tremendous amount of efficiency, the transports either have to come into harms way or become nothing more than activations. And the list becomes less godlike.
Alternately and in the meantime, either play this list (stale, boring meta, thanks) or just bring a pile of snipe and AS and focus the living hell out of the relay squads (with their TON of health :/ )
