I don't disagree, but also the bard's niche is not "I'm totally a full on wizard when it's useful". Back in the past being half caster kept the bard from shoving the wizard aside from the wizard's own niche but bounded accuracy skill changes & making them a full caster allows them to do that. Why is it a problem for bard to find their own niche in generating these effects if they need them instead of using the wizard's niche for them?
Back in the past (2e) my bard was behind the full wizard in casting for exactly half a level... then the bard was level 3 as the wizard was just level 2. They had a bit harder time finding spells and having high int on top of charisma etc, but they were level 7 when the wizard just hit 5.
Then the bard had much more hp and all spells were cast at higher level. 7d6 fireball was better than 5d6 fireball. Chromatic Orb was way more usefull for the bard as was magic missile...
So no. The bard was not a 2/3 caster in 2e. Rather 90% caster. And they could keep up quite well with non specialist magic users. And their chance of survival up to level 7 was also way higher.
