The one thing i remember about the sorc ..pregear.. in D2, was the shortage of mana you almost always had.

Of course, you had mana potions to help with it, but it always seemed like you were just aching for the next mana potion to drop so you could grab it and use it.

I can see a very similar trend in D3 with mana orbs.

So why not give the sorc a spell that gives back mana. In the sorc vid, you can see she has a melee attack, that looks like blueish green claws (or something). This melee attack requires the sorc be close to an enemy, and could easily be given the effect, "generates 'x' mana" for each hit. Kind of like a mana leech.

I feel like this would allow the sorc to be more versatile. Who knows...maybe that skill already has that effect. If it does great. If not, i think it should be considered.

Obviously it's just too early to say the wizard does or does not have mana issues, that all comes down to balancing and fine tuning, and ideally of course the goal is that each class is very playable and not frustrating. Especially at early levels.

Mana orbs are actually the product of a passive skill in the wizard's arcane tree. Since we can't guarantee people will get that skill I don't think it can ever really become the deciding factor in mana regen. It is an early skill in that tree though, easy to pick up, and sure to be helpful.
