Agreed, it's a shame CWA is dead in the main scene, although mad respect to CT for still doing it. Hope to see more clans attempting to do this style of CWA. Single spells is pretty much afk boltswording/afk pilefreezing, and multispells feels way more intense because of the constant moving around and a totally different style of piling.
Both have its charms, but multispells has definately gotten the grip on me (and Veng as a whole). It might be because its new and fresh, but I feel like the totally different playstyle is way more attractive as well.
