Honestly it depends on what class you plan to play as. Being able to have +2 to main stat instead of +1 is great. You lose out some points as you go from total +6 to total +3 but that's not a big a problem as some of those would have gone into stats that you'd have dumped anyway so really you're only losing 1 meaningful point. Beyond that medium armor is great...especially if you don't plan to play a class that relies on dex. Polearms are not great, I hate them, so I see that as a wasted bonus. But Larian are still balancing this stuff so hopefully in the final game there will be something more there.
I disagree with your point about the +6 being overkill, I was going to use humans as my race for wacky multiclass options that use more than 2 main stats. Again though, I'm not here to argue my build ideas or optimizations, I just want the old system to be an optional toggle. I appreciate that you're trying to mitigate my dislike of the new system, but I am simply never going to like it, though again I appreciate what it's trying to do and that many others will prefer it. Have your system, but please don't erase mine.
