Spamming is not thinking before you cast. As of now, we just mindlessly(in 25s) spam RJ and WG and if someones taking huge spike Nourish until they are full. We can spam nourish at 1 second 10 times in a row and it doesn't even touch our mana pool.

In Cata, you will constantly healing but will have to think before you push that button. Everything isn't as fast paced since we will be using nourish/RG/ and HT.
