Gywn is by far the more difficult and aggressive boss. I think people remember Lurker being alot more difficult than he is because everyone was such a noob at that point. I did it backwards and played tons of DaS before DeS. I was all hyped up for this crazy Lurker fight I was hearing so much about and I destroyed him melee only without ever getting hit. I was really disappointed. Maybe Lurk was just having a bad day but Im pretty sure most will find if easy if they go back now and fight him.
