Keen on your experience vs what seems to have been a popular lineup for a while now - Sid leader, ig86, ig88 and poggle + one other (often dooku if 6* or above, sometimes lumi). Have run into a few hk leaders with the same and just as nasty, if not more.
I've run into this combo quite a lot lately and frankly it's a bit tricky to take down and the main issue for me is poggle. Poggle increases the droids speed and offense across the board, and my best chance has been to stun him early with dooku before he gets it in. He's faster than almost all other chars and the igs take down most stuff on their own after.
The best counter I have right now is to use almost the exact same lineup. Any other thoughts?
