How does the shadowskin / shadow wall work for you? I only use this type of macro when I dont think the order of skills is important since sometimes it picks one or the other. But in this case you wouldn't want it to waste a wall when skin is up. Ill give it a try though. Another one I use is /ac convalescence /ac awareness /wait /ac convalescence /ac awareness. There are very few times I would remember to use awareness otherwise, and it gives a bit of mitigation to convalescence which only buffs incoming heals but does not reduce damage.
