Titans need a solar subclass that gives them a solar blade similar to blade dancer but with a flaming katana. Would be yhe most badass thing ever. Warlocks need an arc class that gives them healing bubbles similar to ward of dawn but not as long lasting and with stronger effects. Weapon boost would be way stronger but last for a shorter duration. If they dont get bubbles they need something like a Nova bomb or giant pulse gernade that regens health continuously kinda like the radiance perk. Hunters definitely need a defensive subclass. Void defender type. No bubbles. Just fancy force barriers with weapons and blessing of light. Last as long as blade dancer. Subclass also adds to base defense stats making the hunter less squishy.
