Even if it is Flame Burst instead of Flame Charge, you still need to identify the target. I asked online, and Flame Burst isn't a standard wide effect move. It deals full damage to a target, and half damage to another one. I reffed it uncorrectly last time, and it would be too much of a hassle to fix that, but keep in mind that, from now on, you must acquire a target to use Flame Burst.
Also, never EVER edit a precedent post to tell me something. If I see in a raid that the last post is mine, I generally assume it means it has been reffed already and people need to post their orders still. Always post if you need to tell me something else.
