How to reach 40-50k CP team?

I’m PRETTY sure I have everything done, but I’m only at about 38k CP. Anyone can tell me what/where I’m missing to not be able to hit like 45k?

I have ALL units level 87, except Annerose which I don’t own. I have the entire Gosha Academy for Atk/Crit filled. My entire Awakening skills is pretty much maxed as you know since I have so many units level 87. I have 3 out of the 4 possible Formation for Supporters. My 3 units for my PVP team all has primary and secondary weapons +15 Slvl 5. All their supporters are also +15 Slvl 5. All affinity level 20 maxed. I’m in a top 30 guild with maxed buffs.

So what am I missing? The only thing I don’t really have maxed that could contribute is my costumes which is like 170/772 or whatever, and getting lv70 in stats training. But I don’t believe that those are the difference between me being 38K CP vs 45k CP as it’s too negligible.
