I would take him, but I would remake some things with your permissionm [MENTION=6814006]Thateous[/MENTION].If you're okay with taking over for him I'd be happy to have you. Or feel free to make something else if you'd like.
I would rebuild attributes with focus on either strength or dexterity, not both. And I would lower intelligence and stay with paladin. Ancient oath seems to fit the story. Or I would rebuild fully with Dex/Int and start and remain with bladesinger (although SCAG says it is limited to elves).
It seems 5th edition is not as ability sensitive as 4th...but it still seems wrong to spread the abilities so thin. Paladin gets spells early in this edition I believe it was only at 5th in 3.5? I will read up some more. How were the abilites generated? Points? How many?
