Easiest way to get this done but it has to be done by fairly good players. Take 1 group into the side entrance of strat we use this group usually for getting through that quest (1 Paladin, 1 Mage, 1 Rogue, 1 Warlock and 1 Priest). The second area you get to will be the baroness tower and should only take you about 15 min to get from the side entrance to there. You will not need a key to this area if you take a rogue but if you have the key that makes life simple. The other way to do this is to go with a raid and drop group and loot the pattern. The named will spawn you'll get credit and loot item off him then rejoin the raid.
EDIT: Forgot to mention the pattern is near the building to the right of the baroness tower if you're looking at her. Also there is no need to kill her for this quest. Just don't agro her and you'll be fine.
