Is the trade off in having blizz 2 for aoe fights not worth the small loss in single target? Just curious as I was planning on a SMN as my next class
Enemies all have the same, standard resistance to attacks, 100% damage. You'll do the same against a training dummy as you will Twintania. You can simply ignore elemental damage and focus purely on Potency.

A 50 Potency Blizzard II is terrible and probably won't see any use in PvE from anyone but BLM anyway, or when you're FATE grinding. You'd need 4 enemies to make it worthwhile over weak moves, which is terrible when you look at the actual options the DoMs get:

WHM will have Holy, 200 Potency
SMN/SCH will have Bane and a plethora of strong DoTs to multi-DoT with anyway

Blizzard II being cross-class is in no way a trade-off for Thunder being lost. If it wasn't nerfed, there'd be a case to be made, but it is.
