(He, Him)
Thank you for your report. It looks like a fun character, but not one that speaks to my design critique.Yeeseash. 21 pages of theorycrafting. I'm going to have to go out on a limb and say that this entire thread is kinda driving me crazy. I feel like everyone in here talking has no experience actually playing a blade singer.
Elves are my second favorite race after tieflings, so let me give you some feedback from my game involving a bladesinger.
8 Str, 16 Dex, 14 Con, 12 Wis, 16 Int, 10 Cha.
Bladesinger 7 (game end)
Warcaster Feat taken at level 4
Cantrips: Green Flame Blade, Booming Blade, Firebolt, Prestigitation, Shocking Grasp
Spells: Mage Armor, Shield, Charm Person, Absorb Elements, Detect Magic, Featherfall, Jump, Sleep, Invisibility, Misty Step, Mirror Image, Rope Trick, Spider Climb, Haste, Counterspell, Tiny Hut, Fire Shield.
The starting array I am discussing (which is actually a few points lower than our PC*) is 16, 15, 13, 12, 10, 9 base (or 1pt better than the average for 4d6 drop lowest). Add High-Elf and take the ASI at 4th. And I don't see Blur on your list - did you have it? Additionally, Warcaster is a mechanically lower-power choice compared with the ASI which would give +1 AC, +1 attack, +1 damage, +1 initiative, +1 save, or +1 AC, +1 Concentration, +1 spells prepared.
Any class can be played at multiple power levels and your case is a great example of a lower power BS. In part, it reinforces why I am making that critique. I love the BS concept, it's just the plain-as-day design fault that I dislike, that lead to overshadowing of martials. Concretely, you chose to have a couple of points lower AC than you could have had (and a further point lower than the stat array that worries me), and based on your report you didn't use Blur. I can see how that leads to needing Shield more, and feeling more on edge in each combat.
*That's a PC in the TotYP campaign that I am playing in. Plenty of chance to observe character in actual play.
