Ambivalent. I liked 1 / 3, And 1 / 1. So 1 / 2. will not make much of a difference.
However if I can make functioning character builds each with new perks suitable to whom I am playing as. I will be happy.
If they make a lot of piffle with only 1 or 2 perks of use by being uber perks and penalize you for not taking them. Then I would rather have more then less so I can Roleplay without getting frustrated that I can not end the game how I feel my player character should.
So depending on build choices and perk choices, and if roleplaying has more influence over the game 1 / 2 will suit me fine.
(For example, I doubt FO3 would have had "two skills +5" perks in an every-other-level scheme. They'd never be worth a pick, and not a single person would ever choose one. Whereas I was happy to pick them when it was every level.)
Yes I stopped taking S.P.E.C.I.A.L increases and just took one of these to suit who my pc was. Because they added some background in my opinion. If NV adopts them I would like to see them boosted one offs with more dialogue paths. Than multi picks that have little reason to be there.
