I'm a 54 level human and so far I already have +1 intellect as a Guardian archetype. Not bad I say. I think you get +1 stat after every 10 levels. However I wouldn't know sorry

If this is true I would have 15 int by 70? Plus there is always the dolphin astrosphere for intellect, fortuna chant, and herofetes.

Human is probably the best race to choose I think if you PvP heavily because you are able to regen your experience a bit faster if you and when you die. I think evolution was a great add on to the race. (Maybe thats just me)

Every 5 levels.

lvl 65 human geomancer. 14 int, 13 dex, 13 con, everything else 12.

So sure, if you get high enough humans would be great. And the whole exp thing is fantastic, but not having any sort of regen at all makes it a bit of a drain on vials, and I find myself envying that mugwump eq. But that's just for bashing, I'm not decent enough at pvp to make any comments there.

No idea for warriors though.

Since im a human Celestine level 74 i would recommend going something else my stats are about 13 str 14 int 13 con 13 dex 12 everything else. It makes me miss the days i was a merian I could kill alot more people with absolve then I now resort to kill most with judgement
