I think that the 3 R9s are the tipping point for "worth it." I'm guessing there will be upcoming units that really help the team (hopefully not conq units). The bugs just take time. I don't have GLAT yet, but her team has some complex abilities and uniques, so the bugs are somewhat excusable.
Meanwhile, compare that to Leia and Jabba, for example. They each require only 1 R8 toon, and in Leia's case that toon is an important member of the team. And yet, they're both monsters on offense and can easily cause trouble on defense, even without any omis.
