And tbh honest, extending our mana regen is not that big of a deal... especially since we waste it on us instead of using it on a tank/dps. Fair trade imo.
Not a fair trade(Or...TOO fair a trade?). And it's obviously the reason why you can't cast it on yourself. Because the point is primarily to buff cards. But taking luminous off it and it'd be fine to say extend a ewer on yourself or a balance/arrow if you're soloing.
