While the content of this game is certainly a bit lacking in quantity, I can't think of a MMORPG where it took more than one day to do relevent raid content on farm outside of logistical reasons (e.g. stuff respawned on different days so you've no possibility of finishing it in one day) or political reasons (you only need the top tier, but to keep the peons in the guild happy you got to do some lesser content).
