(mine not yours ) Mine are:
5:Gregory a larger world: because he has no leader skill and his ap rush is so slow
4:Hershel road to survival #1: his ap rush is 66 (fast) and its just -20 ap to 1 enemy and all ajacent to it and up to 3 Teamates get 60 attack To me hes not useful the only thing good is the netrelize.
3:David ties that bind: his ap rush is 66 fast and it does 200% damage to a line of enemies and stuns for two turns. He also has evasion that Makes him dodge stuff So thats ok.
2: Skylar Her ap rush is 66 fast (once Again) she hits one enemy with 525 % attack 70 attack on all teams. Her special skill is tenacity
1:Michonne Shiva force: Her ap is 45 (very fast) and also has waste not. But the bad thing is that she only gains 80 to her.
