Attacking: single techs, nuking, or physical?

[Forge]

I gave my FOmar a level 200 mag, so for normal mode I merely nuked everything with GIfoie and Foie. Now I'm in hard mode, I've started to melee with my Mahu, using Grants and Megid (both at Lv15) for support, for instance, when I need to quickly take out that Hildebear or Grass Assassin. I use up far too much TP being a nuker at this level, although the Lv18 Foie with an Amplifier of Foie and Hildebear's Cane is impressive.
