Pally/pally/druid.
Absolute monstrous ranking potential. You're basically just undead murderers. One pally goes storm shield ded, the other one goes any race champion. Reason for this is you can get poleaxe super early (double vuln on undead) and a storm giant can wield two handed or one handed wrath/silver weapons and upgrade as he ranks into request ranges. You're going to shaft the druids wild time but fuck him, we're doing this for power ranking. You run through academy, get some basics, hit up FoN until lvl 20 or so. As soon as the storm giant gets shield mastery (his skill learn should be shield block) you go to get the ornate shimmering scepter (mid-high teens request) and the poleaxe. Double vulns for everyone. Then you *carefully* do maus. With no other people in the mud the maus shouldn't be super bunched up, so you should safely be able to do it.
Druid stacks natural herbs and is just a decomposition machine. Shield ded tanks, champion uses his abilities to buff as necessary and spell the shield ded if the shield ded needs a break. Once you finish a certain ranking oriented quest you switch to whatever the hell Arboria is called now. You grind that out until 40 or so. Then you switch it up. You *could* do Calandaryl, but disarming is so crucial there and I don't see a reliable way for the paladins to disarm the skeletons. So I'd probably take my holy weapons and go to Maethien or Corte. Probably Maethien. At this point Druid is a heal bot with fire seeds.
I'm 99% sure you could roll up at 9am and hero by midnight.
