"A typical match" insomuch that it is a matchup between two players at rank 30 and 60 currently, and I believe MacChan was around 25 in this fight. If your point is that the highest end of Live Arena - much like G4 Tag and Plat in Classic - is going to be heavily dominated by meta champs, then yes it is typical. strangely enough, players will pick the best champs and teams in a current meta. but, there is also a variety of counters that exist such as bombs, block revive champs (passive or otherwise).
for what it's worth, duchess is almost never being run fast these days. in fact, you are more likely to see duchess at 150-200 than you are 300+ in high end arena.
on top of all this, Quinn accurately pointed out that several strong meta champs and counters were fusions. this doesn't even include free champs like Ronda, UDK who are absolutely doing work. supreme elhain is definitely seeing burn as a counter to some tanky comps. between ukko, pythion, gaius, gnishak, ronda, elhain, udk, mithrala, and perhaps lydia to counter some of the revive heavy nonsense (though we can proc sheep) there is certainly a core for a lot of players to work with. that said, if one has mostly skipped fusions and/or is too new then things will take a bit more time to climb, as they should.
anyway, in the last few days I've really started to see matchmaking level off as players like the ones in your screenshot climbed up. a lot more folks that even if they have meta champs, the blessings are wrong, ban choices are incorrect, in game choices that are poor, etc.
