Somebody suggested a Arcana that allows you to choose a Bloodline, which I feel is totally out of place for the class. But what about something like them instead of Arcana??
So like Anti-Mage could gain a bonus to Spellcraft checks, a bonus to Dispel checks, some bonus feats like Spell Pen, Skill Focus(Spellcraft), Iron Will, etc and Bonus spells like Arcane Sight, Dispel Magic, Anti-Magic Field, etc and then 4 or 5 Arcana that fit with being a hunter of casters??
Another such "style" could be Bladedancer, and then maybe one for using a two-handed weapon, etc.
I am not sure if this should fully replace Arcana or just enhance and augment them. Nor do I know whether this should straight up replace other features like Call Weapon or the Capstone which name escapes me atm
