The "best" team for defence

I'm on a mature server with a lot of guildmates, a few being legit whales. This is a question we often ask ourselves, and do a lot of testing to figure out. The droids can be disgusting. HK (L) 88 JE B2 and 86/GG. Another squad that has shown to be very good is Ani (L) Rey QGJ RG and B2/SF. These teams are of course modded and geared to the teeth, and are not fun to play in any way.
