See, it's attitudes like this that make so many people on this forum so frustrated. When healing is all you need to do, technically, to clear content and glare/broil/malefic spam is supposed to be the "cherry on top," what's the harm in having a few more of those things to serve as proverbial toppings for those who want them? There's no obligation or harm in using them, but they're there if you want or need them when you get to the point where you're more comfortable healing to the point where you don't need to constantly be spamming heals.
Getting more tools does not mean you can no longer enjoy your glare/broil/malefic spam. It doesn't mean you can no longer enjoy your holy/gravity/AoW spam. It just means you have something else you can use instead of spamming. I don't see why this has to be a mutually exclusive thing.
