In my humble, opinion, both potential warriors of FE6 are not-too-great. I don't know about you, but Gonzales and Geese have both ended up spectacularly for me, especially Gonzales for the Hard Mode Bonuses (although I agree, the Lilina deployment could get a bit messy...). My paladins (Percival) always end up pretty sucky, but his RNG might just hate me.
But back to the support thing (this is what the topic is about, right?), The Clarine-Rutger A is good, as well as the Lugh-Ray-Chad triangle (if you're planning to use those characters, but I would), which is Lugh-Ray A, Lugh-Chad B, and Ray-Chad B.
