I was taking a look at Meta Battle and i saw Necromancers have no build there for roaming and after patch our roaming abilities have increased quite a bit, at least by my experience.
If you feel like going on this link, read, make your points and rate, would be great. So we can put Necromancers on a high stand for roaming.
Thanks for your time.
