Mastermind/Samurai/Feywarden What Feats?

[Khrysaes]

So, I have been working on a build, and I am struggling to decide feats.

They are two builds based on LudicSavant's Gunkata build, but combining it with up to 3 rogue mastermind with tandem tactician, from UA, and 3 ranger Feywarden. Probably 4 of each for ASI.

To note, it should have six feats, not in any particular order.
Race: Hobgoblin of the Feywild from UA

Feats
1: Fighter 4
2: Fightrer 6
3: Fighter 8
4: Fighter 12
5: Ranger 4
6: Rogue 4

I want it to work with two build ideas.

Dex based Gunkata:
GunKata core feats
1: Sharpshooter
2: Gunner +1 dex
3: Piercer +1 dex
4: Resilient Dex +1 Dex(starting fighter)
5: Tandem Tactician

Wis based Kendo(shillelagh) build
Kendo core feats:
1: Polearm Master
2: Crusher +1 con
3: Sentinel
4: Tandem Tactician
5: Telekinetic +1 wis
Needs +2 wis.

I don't know what to do about the rest of the ASI to get what I want, OR if 4 ranger is benefiting me over 13-16 fighter. I like the stacking +wis to charisma based skills from both feywarden and samurai, and I can easily manage the Gunkata based build, but I do want the wisdom one..

Edit: 16 Fighter/4 x easily gets the feats since it has one more.

Edit Edit: Alternatively I can go Battlemaster

Any Advice?
