That looks better, but I strongly disagree with the archetypes. I'll start with the Spellbreaker archetype: Awarding the entirety of a feat as a class feature is way too strong. Only some abilities warrant that level of strength and they're the archetype's entire build.
I'm not sure I agree with that. A fighter gets multiple ability score improvements, which can be used to take any feat. Giving a class a particular feat that they don't get to choose, seems reasonable to me. Perhaps unnecessary, though. I'll consider replacing it with something else appropriate.
The Dispelling Strike ability is way too powerful. Perhaps as a once/long rest ability, it's fine, but that's just way too much. I'd say give the following: "Starting at 7th level, you gain greater understanding of the manipulation of magic, learning to undo spells easier. As an action, you may expend a second level spell slot and make an Arcana check against the caster's Spell Save DC. Success allows you to dispel the magic affecting the target, as though with the Dispel Magic spell. After using this ability, you cannot do so again until you finish a long rest."
I agree that it's possible I made this a little bit too good. However, requiring the use of a spell slot AND only allowing the use of it once per long rest seems a little underwhelming ... why not just cast dispel magic? I think restricting it to once per day or requiring that it use a spell slot and possibly making it the 11th level ability would be fine.
The level 11 ability is too strong for a level 11 ability. Make that the level 15 ability. And no spell reflection. That's way too strong. I'll look at the other archetypes after this one is fixed.
Abjuration wizards get the level 11 ability at 14th level and paladins get a 7th level ability that gives them and allies within 10 feet resistance to magic. It doesn't seem unreasonable for an 11th level ability since it is so closely aligned with what the archetype is doing, but I think it's reasonable to want to make it a level 15 ability. I could also make it just give spell resistance (and no advantage on saves) and have it be the 7th level ability. Than it would be a weaker version of the paladin's aura.
I don't think spell reflection is way to powerful if I add a similar restriction as with Dispelling Strike (once per long rest or requires a spell slot). I also think this ability fits very nicely with the archetype. I will make some of these changes when I get a chance ... in the meantime, I'd be happy to hear what you think about the Swordmage archetype. Here is how Spell Reflection used to work:
"Starting at 15th level, when you or an ally within 5 feet of you become the target of a spell, you may use your reaction to expend one of your spell slots and reflect the spell back at the caster. If your spell slot is of equal or lower level than the spell, the spell is reflected back at the caster. If your spell slot is a lower level than the spell, make an intelligence check. The DC equals 10 + the spell’s level. On a success, the spell is reflected back at the caster. The reflected spell uses your spell attack bonus and the original caster’s spell save DC, if any. You may use this ability a number of times equal to your intelligence modifier. When you finish a long rest you regain all uses of this ability."
Dispelling strike also worked in a similar way (essentially a dispel magic that you can cast as a lower level spell).
