As far as I could tell, the +2/+1 replaces any racial attribute bonuses. In many cases, it's actually the same as the racial attribute bonuses by default, though the user seems to be able to reassign them.
So my stoutheart halfling ranger, for example, defaulted to +2 Dex, +1 Con as normal, but I could change the +1 Con to +1 Wis instead. I could have changed the +2 Dex to +2 Cha or something too, if I'd wished. I assume I couldn't have put them both on the same attribute to get a +3 but didn't actually check that.
That's fantastic, thank you for the in depth explanation. I love it. This opens up all sorts of doors - I will communicate this to my Guild now.
I wanted to hold off until i fully understood what we were getting. Do you have any additional info on any additional racials implemented? I assume all the standard ones are still there? darkvision, armor proficiency etc?
I assume most stuff remains the same, especially for races that already had +2/+1 attribute bonuses, but didn't have time to note more. Some folk have posted on these forums additional info they've managed to glean from careful watching of the PFH section where each race was flipped through.
Wolfheart mentions the customisable attribute bonuses in his vid, but I don't think he goes into any more detail either.
It might be worth starting a thread specifically on what we have discovered on this, if anyone is in the mood. I don't have time today, but if noone else collates the info and I happen to find myself at a loose end at some point I might give it a go!
