How do you feel about the heals also being telegraphs for sustained fights? Since players have telegraphs as skill shots as well, the healers have to be careful where they put telegraphs as well. Telegraphs could also be sped up, and have it disappear a second or two before the actual attack comes. This means you'd have to remember the path on top of aiming your own telegraph. I think they could pull off some interesting combinations with this mechanic if done properly.
