I don't mind it, because I kinda like Charles, so I'm okay with him having another shot at the title, but I don't see it going differently. Hence, I am nowhere near as interested in it as in the first time, and then I was already convinced he hadn't much to offer against Islam anyway.
On the one hand, he avoids having to fight more guys and potentially losing the opportunity for another title shot; on the other, he's very unlikely to beat Islam, so maybe waiting for someone else to beat him - a better matchup for himself - would be a better business decision.
