In the latest store championship that I played in. (and won) I witnessed the full power of XI-7's. While at the tourney, someone (newer to the game) talked about how Enhanced Arms was better or slaved turrets in an Ackbar list, but truly XI-7's are the no brainer. With that said... and I know the posts after this will be full of anger and "Why would you ever say this?!?!?" But XI-7's are really OP. There is no single card in the game (that isn't a commander) that simply eliminates things as much as XI-7's. Even Intel officer is only one use per attack phase, but XI-7's plus intel officer is just insane. Long range you can get rid of Brace by the end of turn 2, either that or the ship is probably dead. For 7 points in the same slot you can get Slaved Turrets which limits your attacks to one to add a red die, or heavy turbolaser turrets which is like the weaker younger sibling to XI-7. For more points you can put on turbo laser reroute (decent, but you have to use an evade to make it happen), H-9 turbolaser which if you use Home One who cares about that, or Enhanced Arms for 3 more points to add a red die to your sides.
Again, no brainer that XI-7's is the only option to put in the turbolaser spot.
So, is there a fix? Given this is probably mainly for 2-3 ship lists, but that kind of rocks the meta right now. (I know that some lists out there are winning with more than this, but this seems to be the common core)
This is not a knock on the game because I love the game, even more than X-Wing, but I feel like XI-7's may be the most powerful and yet OP card in the game.
