Last night after 6 attempts we finally downed Freya (guild first). The boss was not difficult but the adds were tough. Particularly the 3 adds; Storm Lasher, Ancient Water Spirit and Snaplasher. Those 3 adds gave us a bit of trouble. For some reason we could not figure out how to kill them. Either we were too slow in killing them before the next wave or the off-tank was killed by the stacking debuff.
Finally the last attempt we got our rhythm and took the adds with enough time to caught our breath before the next wave. Good times!
