It's definitely an interesting concept for healing these telegraphs. But if you think about it WoW kind of uses it a s well for some of their AoE Heals, like healing rain, swiftmend after effect, light of dawn, and the priest thing. Where people need to stack up to get the full benefit from the heals. Of course Wildstar will take it a step further with most spells being telegraph based. Which is extremely interesting. BUT I'm very, VERY please to read they have single target spells in the game as well, I really think you need to have that for tank healing or someone taking insane dmg. I do hope some AoE spells can be placed and that not everything is cone based or based in a circle around you. Though I can see some interesting stuff they could do where you maybe fire something in a direction with a telegraph around it for like 5 seconds and everything in that path getting healed. Or imagine a spellslinger shooting some sort of explosive shot on the ground with a circle telegraph round it and it explodes and heals ppl standing in it, then the smaller particles coming from the explosion turn into smaller circular telegraphs X yards away from the initial explosion and heals everyone standing in those.
