Depending on the nature of the movement, SMN has a few tools minimize the downtime of his casts. For example: T13 Megaflare. You see the cast coming and your DoT has 3 seconds left. Instead of refreshing the DoT, you can use Ruin2, then move while GCD runs and refresh it afterwards. Alternatively, you can decide to refresh your DoTs early if you know that a movement-heavy mechanic will come.

Though you could argue that BLM can do the same, it's not truly right because your FireIV rotation is limited on the duration of AF3 and Enochian, especially the former restricts you very much because you can only use 2 GCDs (3 when switching to UB3) before you have to use Fire1 again.

Another point is that FireIV has a 3 second cast time (no spellspeed) vs. the 2.5 seconds of SMN DoTs. This can be crucial when slide-casting out of AoEs, so SMN might not lose a GCD where the BLM will definitely do.
