FFG has made some great errata changes to rebalance the game of xwing. But what about all of those upgraders that you bought and haven't seen since then? Why won't FFG do a massive errata for all of them? Most would be so simple and would shake up the meta in a big way. Consider the YV 666, the hounds tooth title and maneuvering fins could and should be changed so that people would want to take them or at least be up for consideration. I for one think the Slave 1 title should add that "when equipped you may add a torpedo or missile at a -2 cost. What about body guard from the Star Viper expansion? What about that card that you want to play except its just not quite where it needs to be? Anyways my point is, why leave all of these cards behind rather than leaving the errata to only over powered or poorly written upgrades?

Perhaps because they do not wish to sell upgrade packs only they are waiting for the X-Wing 2.0 release for that massive of a change.

"Misfit Upgrade"sounds like a Rebel- or Scum-only slot to me.
