I've seen a tank just abandon the party in the The Tam-Tara Deepcroft because the party was moving a bit faster then she liked and she wouldn't tolerate not having her way for even a second. This is the The Tam-Tara Deepcroft mind you, where a tank isn't even technically needed to tank if everyone is being synced. Is this the norm? No. Most players in the daily roulette just want to get the low level duties over with as fast as possible.
