Whilst I understand what you mean, Lightning Bolt doesn't benefit Enhance or Elemental any more than Resto. It is a flat % mana now, not based off damage. Its still amazing for Ele and Enha because it means their LBs are mana neutral, and for Ele for example their LBs regen mana, and if they regen mana with no cost then they BECOME mana positive, making you able to spam heal and spam CL more (its currently a required glyph for PvE Ele).
