I'm happy with pretty much any idea of an invuln change at this point, the reason I wrote the idea like that is basically give the DRK something slightly different and yes it could be used offensively but with 5secs of zero mana and resource gain, if the rest of those changes are done it means you're a sitting duck for 5 seconds, no self heal abilities. But ultimately yeah I like your idea too have Frey fuse with you and give you mega regen.
Pretty much all DRK weapon skill animations could be used one into the next. Due to the GCD, your character reverts to their in combat stance at the end of each weapon skill. Every weaponskill for DRK has an initial attack swing then a final swing before the reset to in combat stance, this is true for all moves, so it doesn't really matter which one you use after the other.
Returning Dark Arts in it's original incarnation, which was to modify certain moves, giving them additional damage and a status effect would be nice but would require some serious design work. The issue is that alot of the status effects didn't apply to bosses so made them moot, would be good to maybe change them into buff and debuffs. Instead of us being a budget warrior we could be the buff/debuff tank.
