Tbf to Ace, if he was a coward he'd have hit VM with aload of his Pantheon mates, instead he chose to stick ok if out and actually tried fighting TEst, who are imo the strongest alliance around, so kudos to him. He easily has the most to lose and yet chose to stay and fight back, even a losing battle.
Of course the alliance hopping and war avoidance all suggest coward and I'd agree, but at least he stayed and took the hit this time.
