Lackluster. It's essentially just a weaker Wizard who can turn into a Familiar.
To your point..wizard is waaaay more powerful then its supposed to be. They are definitely NOT supposed to be learning cantrips and cleric spells from scrolls.
Other then that id say they are actually pretty equal if you go circle of the land. Just waaaay more survivability as the druid since you can essentially have something like 60hp to burn through
I did a Wizard playthrough without the omniscient scroll cheese and they were still extremely powerful.
For sure. Both wizards and druids excell in versatility, and both can really be what ever you build them to be. Honestly it seemed to me, though, that for blasting, the warlock could really pump out some consistent numbers.
Getting off track a bit, but yeah, Warlocks have been my favorite class so far. They're not as diverse, but they consistently perform well. I was really hoping that the Druid was going to pack some serious magical punch, but the design ethos for them stayed true to 5e in this case, unfortunately, in that they have a lot more utility and a lot less raw firepower.
