The more I have played the game, the more I have come to appreciate single classes over multi. Having access to higher level abilities almost always matters more than multiclass synergy for me. I also prefer strength at low levels over classes that are strong with ideal gear at lvl 20. A single class ancient druid kind of exemplifies this, mushrooms at level 1 and early powerful insect swarm can carry the early game.
I absolutely agree. The more I play the higher I value single class characters. In a full party that is. Having access to higher Powel Levels earlier is much more important and has more impact in my opinion than having a bit more resources and a "perceived synergy advantage". Because most synergy effects don't need to be done in a "self-contained" build when you have a party.
