I've suggested something similiar in the past:

Get rid of the crystals alltogether, and make the buffs a passive bonus granted upon completion of AROP. Grant both buffs to both factions.
Factions do not = combat style. Only ROP mentions that Helians are "slightly more scholarly" which I suppose infers they have studied the use of Primal magic a bit more, and sounds more like a mentality or attitude. The lore also goes on to state that some of the best Primal Healers were of the Lunus political faction. However Chiconis is where the Primal Trainer is, who is of the Helian political faction (so maybe that rubs off a bit more on those who hang around her). But her training is available freely to all dragons. Same can be said for melee combat traing available to all dragons as well.
The ROP bonuses, Path of the Lunus (+20 t&c, +40 flame resist), and Path of the Helian (+20 Primal, +20 spirit resist, +20 ice resist), are enough to satisfy the lore in the respects that "Lunus prefer to fight, not talk" and "Helians are more scholarly" (which infers maybe a little bit better study of Primal magics).
The dev's years ago made the mistake of tying the political factions to combat styles (in an effort to create some combat differentiation, good intentions poorly implemented).
Creating some combat variation is fine, but it should not be tied to political faction.
There are still dragons around who did Rop BEFORE any of the later, political tied items came along: Breath of Ice (used to be Helian only), Breath of Lightning (used to be Lunus only), Fangs of Fury crystal (Lunus ancient only), Primal Rage crystal (Helian ancient only).
Thankfully the devs decided to untie the Breath attacks from the factions awhile back. The only thing left to untie is these crystals. Get rid of them completely. Make the bonuses passive.
Tying the combat styles to factions might have worked, had there been a little better spell inventory for Casters to use. Prime Bolt is way too slow, Primal Cast was very late arrival (but thanks dev's for this), and healing spells were only a few hots and one heal ability on a 5 minute cooldown. Now we at least have Primal Health. But these changes wouldn't be enough to make a caster a viable combast choice in most situations.
Truth is, the Dragon Adventure school is a Hybrid school that is primarily melee. Similiar to Reaver, Paladin, Knight of Creation for examples. But those schools have much more filled out spell inventories, so even they are better at spell usage than Dragons are.
Dragons are supposed to be "Masters of Primal Magic", however this never really materialized. Perhaps too much spellpower in a strong melee class would just be too much.
Giving all dragons both sets of abilities passively is simply the fair thing to do. It isn't going to make a huge difference to mainly melee fighters unless they chose Helian when doing Rop. And let's face it, the Dragon school is mainly melee. This is just the way it is. Everyone who chose Helian got a nerf when the AROP crystals came out. This will resolve that.
