Party leader creation help

[[)3Z]

I want to create some sort of a party leader character. The most obvious choice seems to be Tactical Leader, but that one seems pretty useless: granting team feats seems to be meaningless since a lot of those are too good to ignore - party members will eventually get them anyway. The diplomacy bonus feels more like a compensation for low charisma.
Any suggestions on how should I build my character to fit in that role? I don't want just some sort of a buff/debuff character (any caster could fit in there), but rather one that feels like a field commander. A party leader that's born to order men around with a silver tongue (that probably means high charisma).
I'm aiming for this party composition:
Valerie as tanky melee, lots of AC and a dazzling display or trip focus;
Octavia as Arcane Trickster;
Tristan as a healer and divine nuker;
Linzi as either a pure bard or a duelist (depending on the main character build)
And I'm not sure about the last slot - probably the alchemist gnome.
inb4: I don't want to go paladin because of alignment restriction, I want the protagonist be more resourceful. A true neutral or, perhaps, CN - could care less about moral code or laws of the land.
I want to play the game with this character on normal settings, so pretty much anything fitting the description should do just fine, I guess.
Plz, help.

Hmmm, maybe a bard?
