This has been countered many times in the past. We have an overabundance of repetitive healing buttons. Sage has roughly 20 different buttons for healing, yet in most pieces of content, can rely on around 4-5, with only 2 comprising the majority of that, for example. Condensing healing actions into a more manageable number not only gives room for a few more attack actions, but also makes it easier for less experienced healers to learn the differences between their healing actions more easily. The burden of knowledge on having so many different heals is often too overwhelming to the beginner right now.
