They would feel better because they would no longer have the "assist target" mechanic. This would make playing a paladin feel even more like playing an SK, who generally gets to remain on target while casting most of their abilities. I'm not advocating that style change so much myself. Paladins have a higher burden of situational awareness then SK or warrior because they have to target other players often times. I think paladin mains like that game play aspect (I do) even though we have been trending away from it the past many years. The reason Light is not used is almost entirely because of the Timer 9 conflict with Protective, so it fits your argument that Protective already addresses. Burst also superseded Light because of cast time and heal amount (we don't care about mana efficiency on an emergency heal). The two spells were designed as emergency heals (not spells that were in a weave, in fact they couldn't be) and have since taken on the aspect of basic combat spells as embodied by Protective. It's been an evolution. Burst recast and lockout times prohibit its use less so then originally as they are less severe now. The Devs can continue with spells like Protective, Denouncement, Refute, and Valiant. The Devs can improve their efficiency and focus which is really a different argument vs targeting mechanics.
