Soloing as a mage and necro

[brokenpromise]

Long story short my PC took a fat shit several months back and I was testing out both mage and necro. I'll make this brief

I know everyone says necro has more utility. That's undeniable. My real question is does necro have more solo options due to utility? They can root rot, fear kite, charm etcetera etcetera. The mage pretty much just chain summons.

Is the mage class limited on what they can solo and farm? Let's set aside things like feign death. Does necro have simply more solo options due to utility? Let's say mage can only solo at X because they simply cant chain cast enough or effenciently enough. While necro can solo x,y,z because they can fear kite, charm, root rot. Or can mage solo just as much things as a necro, despite chain summoning?

I am mostly solo and farming.

I am very close to just going with necro. They have a ton of utility and a lot of different ways to solo. I love the mage class but I dont want to find myself in situations where I am very limited on what I can solo and where.
