I recently flew 2 TLT Aggromech Ys and IG88c against 4 TLT ys, that was interesting. I had to kite with my Ys so only 1-2 could hit them, and I could focus fire one of them. One broke off to take IG but I was able to get behind it at the corner or the board with an asteroid in the corner spot so the Y couldn't get away, them I kept bumping it from the back and taking shots at r1 whenever I could.
On the other hand I one played round 1 of an escalation as Kenkirk vs Han or Chewie, that was boring as hell.
