So yeah, Fire is fun. But I think I enjoy the Frost and Arcane play style better. If I invest in either of those artifacts, am I gimping myself since Fire is the "hot" spec now dps-wise? I could play fire, but, I just don't think it's my preferred spec.
Also, I assume picking one artifact to get to rank 13 first is the best course? And now spreading your power between a couple?
