If you bring none of those, Dooku is going to be a problem.
That's the key. Personally, I think the issue is that he is the only character at low-rank that can wreak havoc on a team (under a Nihilus lead) if not specifically countered.
My arena team can pretty much take any team of equal level and gear except a Nihooku (I don't think that's going to stick, lol) and Chaze. The only difference is, Chaze is much harder to farm and requires both of them to be alive. One time I had a 5v1 situation against a Nihooku and he killed each team mate one-by-one.
TL;DR He is OP with Nihilus lead at lower levels if not specifically countered which is not something players are used to doing at lower ranks.
