I usually love buff spells. But the concentration mechanic is the problem for me. I do not like it at all, not one bit.
Concentration is base 5e though rn with how wonky some stuff is implemented it doesn't work as well as it should. Mage Hand dismissing a familiar cause its concentration summon when a familiar is not concentration at all is one thing. Also noticed with the staff that provides resistance that if someone casts something on me, I break concentration even though the thing cast was a buff.
Buffing gets better and better at higher levels in 5e though and there are other things like being able to inspire people and give em temp hp or providing bonus die as a bard.
