Yeah, I would never give bards wizard features, thanks. All I usually hear on this forum is about how bards are great... so if they are lacking potency, maybe it is a personal problem?
I loved bards in 1E, but they were hard to really get to if you played more by the rules. 2E bards were ok, but I never cared for Bards once they added all the fluffy crap since then.
IMO bards should not be full casters, more like 3/4 casters or 2/3 even. They get mad skill abilities in 5E, can fight pretty well as much as many battler-types, and then lets through full spells along with other features on top of all that.
You love bards, that's cool. I don't and with their design in 5E, never will. As far as Sorcerers and Warlocks go, I think one combined class mixing their features in some manner would have been better. But hey, to each, their own, right?
