I'm not sure necro from ArchAge is the best example. In my experience, that role was very niche. If you went the DPS route with it, you could get lucky and CC people to death, but most good players would only see a necro DPS as a minor annoyance. Not to mention the DPS the necro puts out is subpar at best. You would have to get basically every CC skill from witchcraft, and I just don't see a necro DPS as viable build. If you were good enough of a player to make it work, than more power to you; but the necro DPS in ArchAge is really a trash build for the average player. So for those reasons, I really don't see that example as proving the point of support role working well in action RPG genre.
