they overtake map control splitting their players through all the map on their own, but their best tool is their teamplays so c9 just micros one of theirs and win all the advantage
They haven't changed much since week 1 and are extremely protocol based. Makes them very predictable and easy to anti-strat. Taco has also not been performing which makes it very hard to do well in this duelist-dependent meta. Don't think it's much more complicated than that.
