I limit my use of potions to PvE and in that I use Spell Pots and Trash magic pots for DD and healerDD activities.
The range of potions is lacking in my opinion:
-> A higher magic restore pot, say 10k magic
-> A major beserk only pot (low run time)
-> True sorcery pot with both minor and major buffs
-> True intellect pot with both minor and major buffs
-> Inner element pot which gives a small buff to a particular element dmg type as well as a weakness to the other types... say 10:5:5
Etc...
