I have upgraded the Ultimate Guardian to orange today... Turns out he is still garbage. His main issue is not having a skill prioritization based on current hp. Upon starting a fight in a pvp event or after resurrecting with Capricorn talent on pve stages, he will always use his aoe buff rather than heal himself, regardless of how many hp he has. I am losing a lot of fights/stages i easily won in the past with Lord of War just because of that. Guess i'll kick him back in the support crew and forget about him once more.
