I would not, however, keep the maximum hit points at level 1 - that simply makes multiclassing unfair based on the order in which classes are taken
Does anyone knows if folks at Paizo already decided what rule will be in the final release of Pathfinder ?
Do you think they would let these options open, or they will decide that one of them will be the "canon" ???
If yes, which one ???
We will start a new campaign using pathfinder beta rules but we'll probably switch to final rules when it will be available. If we play with Con Stat + Max HP and the future rules says otherwise...
