Is it me, or is college of glamor a tad underwhelming?

Beguiling magic seems to say when you try to enchant someone with a slotted spell, you can charm someone else for a minute?

Mantle of Inspiration seems great, but it burns a inspiration die, which already feel scarce. So cant use this too many times.

Mantle of majesty is... odd? Requires you to make concentration saves to keep it running for the full minute. I suppose a free casting of Command per turn for one minute is cool, but  1/lr is a bit steep. 

Keep in mind that when you reach level 5, all your Bardic Dice come back on a Short Rest, making it a lot easier to throw around abilities that expend them.

And that you get one free Mantle of Majesty per Long Rest, but you can use a spell slot of level 3 or higher to do it again, as many times as you have spell slots of that level.
