You’re welcome - but I thought your intent was to ask a question, not make a statement defending your method of training your horses. Whatever works for you is just fine. Most of us posted back asking for specifics, since “green” and “broke” means different things to different people.
There are many roads to Rome.
But not taking a horse hunting until it has at least a basic education, that’s a no brainer. And any discipline can provide it; the hunter ring is not necessary.
Before you get all offended, that wasn’t an insult. A beautifully trained dressage horse is a joy to ride in the hunt field, as is a cutter, a plow horse, an eventer, or a trail horse.
If the horse can walk, trot and canter/lope, can be ridden in an open area without losing his/her mind, trot a crossrail, is sound, isn’t a kicker of horses or dogs, and has all his marbles, that’s pretty much the basic requirements to be introduced to hunting. Ideally the horse would hilltop before joining the field, so you can still be working on jumping if you want. Or - you could wait until the horse is a competent jumper. But the basic education remains the same across disciplines.
Where the horse goes from there, and how to actually turn a green field hunter into a trusty field hunter - won’t be found in the ring. And I think that’s what we were trying to help you with. The most perfect square halt from a dressage horse is beautiful - but how to take that lovely halt and obtain it when 30 couple go howling by, followed by 60 galloping horses, on a frosty, windy morning - that ain’t gonna be taught in the ring. 
Ask me how I know that.
