I haven't heard particularly good things from my friends who went into the TESO beta. Actually, quite the opposite.

There will always be trolls. The larger the group of random people, the more likely you get trolls. You really shouldn't be allowed to queue for CT without a full group to participate in advance, at least that will allow players on particular servers to filter out their own trolls if they actually want to beat the dungoen.

Sadly, it's just another mark on a very long list of things that have been badly mismanaged by the dev team since long before beta, just like everything else.
