Love it!
The person who wrote this is well... VERY bad at designing characters. You've got to be a bit dense to advise someone to play using Volo's inept Hobgoblin write-up as literally anything but a Wizard. If you go for a Martial melee Class, you are way better off going for well... anything out of the PHB except Gnomes or maybe Tieflings and virtually everything else in this book.
Seriously-- just how dumb do you have to be to look t something that boost your intelligence and gives you martial weapon proficiencies and otherwise.. a once per short rest ability to turn a near-miss into a hit so long as you stick close to the rest of the party (that isn't a 'combat bonus' much less plural) and conclude that you should play a class that nullifies the weapon proficiencies and for whom intelligence is a dump stat?
While if they had been completely ineptly designed in a way to just "fill a gap", then I am sure they would make a decent character if matched with a melee martial class. But they weren't. So this advice is the worst that could have been given.
