BH I'll admit I included primarily because I use them in arena. However, I'm finishing top 5 daily, so I think that justifies their inclusion. They can also score over 1m in P4 HAAT on a good day. They are also interesting in the gear breakdown as one of the most expensive teams available, which should be known if someone is interested in starting them up.
Resistance you are right, I should include them. They can score well on HAAT, and have become even more interesting with R2. I left them out because they arnt all that popular, but yes it's unfair to include unpopular BH but leave out unpopular resistence.
FO however, I have not yet seen as being truely viable anywhere. If you have video or other evidence that they are viable as a team (not just Kylo or phasma independently), I'll include them.
