That's true, but the problem is that they get to castle age 2-3 minutes behind everyone else. IF they get good defense or pocket, they can work well, but they could just as easily end up flank against a Chinese, who will have more like a 5-6 minute advantage.
Huns do fine in castle and imperial, but most probably would pick even Vikings over them.
