Lower Score in Coliseum after Unlocking Marquee

There are multiple problems here.  First, we don't have anyone with a leadership ability yet.  We won't get one until either Cassian or Partagaz is realeased, so we have little synergy as we did last time with everyone getting every tag.  Second, a lot of the coliseum opponents get buffed stats based on number of times they are hit between turns.  Thus, with the one extra toon, you are getting more hits in (even if they do little damage) which ramps up the enemy which leads to getting full team wiped a lot of the time.  I'm at 38, 37, and 36 in release order of the new toons.  So far I have gotten to tier 4 on zeffo and dryax.  Both those tier 4's are rough at this stage.  I was lucky to get 19% and 10% respectively.  My run this morning only got 1%.  I am hoping I can tier 4 AT-ST this afternoon to hopefully get Kleya to 39 since that is a nice protection bump.  At this point I'm really getting worried about being able to hit 40% in order to get the gear to advance past level 39.  I didn't really track everything last time, but it sure seems a lot slower for advancement this time around.
