So let's assume we have a "normal" Paladin healer, meaning one who does not play perfectly but still makes mistakes and wants to focus on doing the most important things right (and not care about minor stuff). Would the following be a good strategy:
1. Make sure to always be casting something, when in doubt just spam Holy Light on someone.
2. Make sure to always cast Holy Shock on cooldown. Make a Weak Aura or timer and press it as soon as it's off CD, it doesn't even matter that much who you heal with it as long as it's used off cooldown.
3. Use your Prism on cooldown and cast Flash of Light in between Holy Shock in case incoming damage is severe (replacing the HL casts you are always spamming otherwise).
4. If you got the time for it, eventually cast your EF, but don't worry about it too much, doing 1-3 right is far more important and even if you never cast a single EF in the whole fight you don't really lose much. Concentrate on 1-3 to improve and only start worrying about EF once you got these basics down properly.
Yes/no?
