I've used it on kavil and I felt bad after he dominated that match and the other guy just had to watch his aces being chipped away turn by turn.
They should of been a point more.
But then again, you always brag about how you dominate each game with the Tie Defenders and I don't hear anyone saying that they should cost more. I've played a game two weeks ago in a tournament against a 4TLT list and I crushed it. In another tournament we had, a 4 TLT list ended up last. Should they be 1 point less then?
TLT are just fine. They are part of the current meta and must be taken into consideration when going into a tournament. Just like Palpatine+Aces, Regen ship, Stresshog, Dual IG, Swarm, etc. If you bring nothing to counter it, or don't have a plan, you can expect to lose. But that's on you, not the TLT.
