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.

The extra effect to give an enemy the Charmed has a nice synergy with Mantle of Majesty because they automatically fail the save against your Command spell. So you can cast something like Dissonant Whispers on one enemy, Charm a second, then your Command spell goes through automatically on that enemy. You could also split it up to do some control on 3 different enemies if the situation calls for it. It is some pretty good control.

My view is that Glamour is a "win more" sub-class. It's really good when you're facing a battalion of nameless mooks that you could easily defeat in a dozen different ways but generally poor when you're facing more serious challenges. It's akin to a spell like Hypnotic Pattern. As one option amongst many, it's a decent spell to have in your arsenal. But you wouldn't want to play a class that could only cast Hypnotic Pattern.

Beguiling Magic -- one free use, reusable by spending bardic inspiration, charmed or frightened effect without concentration.  Includes two additional spells prepared at low levels.  This is a decent ability that gets better as more uses of bardic inspiration become available, more spell slots to cast charm / illusion spells become available, and save DC's increase.  

Mantle of Inspiration -- easy access to a good quantity of temp hit points.  Also good but the resource also competes with bardic inspiration and beguiling magic for resources.

Mantle of Majesty -- one free use, allows spamming the command spell, costs concentration, additional uses available for a 3rd level slot or higher.  Includes another spell prepared.  This is a good ability.  Being able to cast command repeatedly as a bonus action without costing a slot is excellent.

Unbreakable Majesty -- turns hits into misses, doesn't use concentration, recovers on a short rest.  This is decent damage mitigation.  

Overall the college grants three additional spells prepared, some excellent alternative uses for bardic inspiration, a few bonus abilities, and the ability to spam the command spell.

Glamour focuses on traditionally typical bard tropes of enchantment and illusion, and I think it does it well
