Well he did beat Gamrot, who outwrestled Armen pretty recently. Safe to say it was worth having a try at beating Armen who had sat out 1.5 years a win could have earned that elusive title shot. I guess he could just threaten to retire or creep up the rankings without fighting like everyone else.
The best should be fighting the best. Only 1 person can win in a 2 person fight. Who cares if he occasionally takes a loss against top 5 opponents.
There was a time in MMA where a loss didn't mean you were done, because the best all fought each other regularly.
Not everyone gets to be the champion. Just enjoy fighters actually wanting to fight other ranked people, instead of sitting out to wait for a shot.
