Of course you can, even without a GMV - just don't get hit. xD There's a ton of HP gear out, now, though, so you could probably still tank (for blade spam or galvest or whatever) - you'd just be spamming cure more often.

While galvesting, you can spam terra, but if your targets are already within range, you could just spam wind blade. I don't think monsters generally last long enough anymore for galvest to be all that useful except in very specific, high-spawn or specific-location-spawn areas (ice dungeon 3, any phantom school room, specific event maps, etc).

As for potion consumption... Wind blade at very high MA may be the most efficient spell you can get, whether you're 50 or 250. At lower levels with very high MA, cleaving terra is also incredibly MP-efficient if you can OHKO mobs with it (it's possible with myshop at 70-80), but terra is harder to OHKO with (and huge mobs generally become more and more sparse as you level).

Mana storm is really slow to train with... but terra + storm isn't so bad. If you can get some good MA gear, this combo becomes a killing combo, and terra is so accurate that you can actually hit 150+ monsters the moment you get the spell (although storm has kind of crappy accuracy).

Wind blade + MR or terra is much faster, though, I think.
