I really hope they do a better job this time around. I wasn't a fan of having to sit and rest for 5 minutes to get your HP/MP up. Adding how necessary it was to have a Refreshbot in any kind of group environment, I think they missed the mark.
They tried to make it easier, though, through drinks, +MP regen gear/traits/etc, buffs, whatnot.
Here are some ideas:
1. Have your character have natural hp/mp regeneration outside of combat, coupled with a "kneel down" type of regen, to make it faster.
2. Have a majority of your regeneration come from cheap, easily obtainable food/drinks(ala WoW).
3. Give more jobs the ability to regen MP during combat, to avoid absolutely needing X job.
4. Have HP/MP potions actually worth a ****.
I'd be happy with any of these, just so long as they avoid what they did last time. >.<
