saw like one player with one part of level II gear so far
he must have gave it a shot and then be like "nah, too much of a hassle"
of course it would provide better stats, however its simply not worth getting overall it seems
the majority of players is proof for this, just look at their gear - there are those who take the effort to go for 115% gear and those who stick with 106% - all level I gear along with some level III drops from raid
