Kinda hard fucks his 'only a god-elf can beat a god-elf' martyr complex. People don't take paradigm shifts well.
Now that you remind me, he's not even a god-elf yet - Solas does not regain his full power until Flemeth/Mythal sort-of sacrifices herself to do that, and that's only in the post-credits scene of Inquisition. Since the Epilogue occurs shortly before 'The Final Piece' (the Inquisition main quest stage in which the Inquisition goes tothe Well of Myrhal to finalize prep for killing Corypheus' red lyrium dragon and thus disrupts his 1-up supply), Solas isn't remotely there yet. I will tweak the Epilogue text to clarify.... looking back, the reference that was clear to me was not necessarily clear to everyone.
Plus, Hawke and party might well be able to help them kill the fucking thing
without taking Flemeth's deal. (Particularly since their tadpoles are gone, and thus their BG3 in-game level scaling nerfs are gone... and on top of all the badassery and level-upping they just went through some of the canon origin party were
very high level even pre-game before the tadpole temporarily knocked them back down. Gale in particular was canonically Wizard 18+).
(add) Ahahahaa, I just realized that it's even better. Because assuming Hawke did the relevant sidequest chain (which my Hawke did), then Hawke is one of the only (correction) three people in that entire generation of Thedasian history to fight and kill a High Dragon before. (DA2, the act 3 mine pit quest chain finisher).
And one of the other two was
the Warden-Commander, in DA1. And the third was the Inquisitor.
So when Hawke steps up and says 'Dragon hunt? I got point. Watch me smoke this chump', the Inquisition has every reason to let him try. He's not only got high rep (as dismal as the Kirkwall situation ended, remember that Hawke's generally believed by all to be a world-class badass from his prominence in it) but he's literally the only proven great dragon slayer they have except for Lavellan, who's got to be in rotation to take Corypheus.
(add) Correction. Cassandra's also fought one... but she was riding another dragon at the time, and it was one of those lucky fluke things. Only the Warden-Commander, the Inquisitor, and Hawke have straight-up gone at a High Dragon on foot and walked out with new dragonskin boots.
And Hawke is wearing BG3 legendary gear and combines DA2 warrior talents with 5e paladin powers. He's got the Adamantine Armor (immunity to critical hits, damage reduction, and stagger opponents who melee you), the Giantslayer sword (double damage and even more +damage on huge opponents), and the Helm of Balduran. (Constant regen and immunity to stun and critical hits). And all his templar-paladin powers for doing even
more damage to a corrupted creature... which the Red Lyrium Dragon is! He could almost SOLO the damn thing, and he's got his party along with him...
plus the entire DA3 crew!
*snerk*
Hawke might only be coming in at the very end of the DA3 main quest, but he's definitely not going to be an afterthought. He'll be like the Final Battle NPC that gives the hero a pass right through a beef gate that was keeping the hero from even trying the end boss fight until all the prior quest stages were cleared. (Ironically, such an NPC is canon to Inqusiition - Morrigan is what they throw at the Red Lyrium Dragon in the actual game. However, given the deal she has to make with Flemeth to get the power to do that, even Morrigan will likely be glad to just let Hawke facetank this shit.)
(add) There's also that Shadowheart is carrying Selune's Spear of Night... and while in-game mechanics it's just a boosted weapon, remember that the lore version was originally forged by Shar to kill an unkillable celestial before Selune recovered it and flipped it from evil weapon to blessed weapon. Corypheus probably REALLY don't wanna get poked with that thing.
