make sure you're getting your enchants and gemming right. always use int or int+stat gems. also dont forget your Cooldowns while you're gearing up. Avenging wrath with Holy radiance will feel like you just dropped Tranquility(Druid's large AoE heal). As far as Glyphing make sure you're maximizing you're Word of Glory heals. what'll feel like a good quick rotation of heals will be Holy Shock, Flash your Beacon (Given that you're using the Tower of Radiance talent), then Word of Glory a target; Holy Light a target if you're waiting for holy shock on cooldown, then rinse repeat all whilst using Judgement.
Getting the right gear is key too.
You're gonna want to get the Core of Ripeness from the Justice Point Trinkets. Do your Tol Barad dailies to get Mandala of Stirring Patterns. If you can get a Darkmoon Card: Tsunami use that instead of the Mandala. Try to find a Blasksmith to get you started on some higher gear. once you can get to the Zandalarai Dungeons things'll speed up. My gear blew until i could get into those. From there you're gonna want to get the head and chest given that they'll be your best pieces for those slots until you can get replacements from raids.
I hope all this helps you.
