Summoning mobs are soloable by bards and you don't need selos to achieve greatness!
Believe in yourself.
I haven’t barded in years and my bards gear level is best defined as: thurg quest gear and the rest is “meh”. I have no interest in trophy solo kills on my bard.
If I want to solo something worthwhile, I’ve got a bag full of level 60s that can do it more efficiently.
