Just got back after a 1.5 year break and have 2 bil from minions, what should I spend it on?

[EzraYeet]

Last time I played was on crimson isle update, and I have no idea what's changed and how outdated my setups are for dungeons. Any advice/info about what's new and what I should get would be greatly appreciated.
