whats the best mythic path for a martial? i want to be a legend but this comes really late game when you are already OP.
You can't go wrong with Angel. Angelic Halo boosts your entire party's defenses and lowers your enemies' saves, at high levels you also never have to care about energy damage and mind-affecting stuff. The spells are insanely powerful, even if you only use buffs. You can heal, dispel conditions, and become outright immune to everything Communal Ward Against Weakness. Abolish Guile increases your damage by 50% against 90% of the enemies. Overwhelming Flames with Great Cleave clears crowded encounters in a single swing.
If you're worried about having to be a goody two-shoes, keep in mind that 99% of the times you can lean more on the Lawful part than the Good one of your alignment. I can't remember a situation where you can't act as a merciless punisher.
