For D2 mercenaries, I use a ranged merc (act 1 or 3) when playing a melee character, and a melee merc (act 2 or 5) when playing a ranged character. Give them good armor, a good weapon (doesn't matter with the act 3 merc...) and ideally life leech (again, doesn't matter with the act 3 merc...). Remember that you can feed mercs healing pots quickly using your belt hotkeys while holding down the Shift key.
For D3, the warrior class is taken care of with the barbarians... I'm really doubting that the paladin will be back "as is" the more I think of it though (scepters + shields + auras). I will say that I expect there will be an aura emitting class though... perhaps some type of battlemage. I like the change to witch doctor from necromancer too... I never played necros. Tried a couple but didn't like them at all.
