Basically - I'm Level 33 and in early Act 1 Nightmare, had played co-op through normal, but have been left behind by my party so I'm solo now. My build has Gargantuan do the majority of the tanking for me, but I have a few questions about followers:
(1) Firstly, is it very advantageous for me to have one?
(2) Which follower is best for a WD? I'm guessing I want one who can tank and I can stand behind where possible
(3) Are they very expensive to buy/maintain/resurrect?
Thanks in advance for any advice.
