Best squads for phase 1 of heroic sith raid

In all fairness my squads aren't in the best of shape. As a free to play gamer I can only do so much and lately I've been trying to keep up with my jedi revan squad since they are my everything squad right now while working on separatists for padme and geo territory battle. So yes my participation is lacking its moreso that I dont have other strong enough teams to add in for phase 1 and the feeling that only a few guild mates really put any effort into phase 1 because it seems like the same very few people put in the higher scores every run. Otherwise we clear phases 2 thru 4 no problem. I'm part of a guild with 48 members and we have a somewhat strict entry galactic power of like 3 million or more. My best guess is either the raid has gone stale for most of us or it's just bad timing but it just seems odd that it only started getting bad within the past 2 months give or take.
