I have built my team based on the "4 must haves" for Giant B10, but for some odd reason, I still can't auto it. Can anyone let me know what is wrong with my team?

CORE TEAM <LEADER> Acasis Wind Sylphid 6* Lv. 28 [HP: 15891 | DEF: 535 | ACC: 79% | RES: 43% | SPD: 174 | Swift+Focus @ SPD / HP% / ACC%] Ahman Light Bearman 6* [HP: 30446 | DEF: 758 | CR: 87% | SPD: 107 | Violent+Blade @ HP% / CR% / HP% - still trying to get 5* or 6* crit rate rune so it'll hit 100%] Shannon Wind Pixie 6* level 34 [HP: 15633 | DEF: 687 | ACC: 60% | RES: 39% | SPD: 111 | Despair+Focus @ HP% / HP% / HP% - tried slot 2 spd but too squishy!] Bernard Wind Griffon 5* [HP: 14492 | DEF: 725 | ACC: 43% | RES: 40% | SPD: 164 | Swift+Focus @ SPD / HP% / HP%]

THE "FIFTH" Delphoi Wind Undine 5* [HP: 17601 | DEF: 678 | RES: 45% | SPD: 139 | Energyx3 @ SPD / HP% / HP%] - increase ally wind attribute's defense by 40% - tried her as leader as well, still fail. Darion Light Vagabond 5* [HP: 23897 | DEF: 564 | ACC: 37% | RES: 24% | SPD: 113 | Blade+Energyx2 @ HP% / HP% / HP%] - the reason for blade is because of my 6* HP blade rune. tried using him, but doesn't seem to help much.

(B8 ONLY) Geoffrey Fire Viking 5* [HP: 12503 | ACC: 100% | RES: 23% | SPD: 110 | Focusx3 @ HP% / HP% / ACC%]

OTHER MOBS THAT I HAVE Belladeon Light Inugami 5* [HP: 11865 | DEF: 834 | ACC: 12% | RES: 46% | SPD: 168 | Violent+random @ SPD / HP% / DEF%] - still waiting for good Violent runes. Previously swift+focus but that has been passed down to Acasis. Julien Wind Phantom Thief 5* [HP: 9203 | ATK: 1370 | CR%: 61% | CDMG%: 164% | SPD: 131 | Rage+Blade @ ATK% / CDMG% / ATK%] - tried it, too squishy & died between waves. http://imgur.com/7noaLjC http://imgur.com/JnEr8Lt However I'm able to auto B8 with 100% success rate, just don't know how to push it to B10. Appreciated it if anyone could help me...
