The thing is, if they put allocated stat points into D2 now, I wouldn't care because the stat system is broken. But in D3 there's a stat system that look very interesting, and I really want to play around with it. The fun of planning builds is of course even more fun when you have more parameters. Since they axed half of them, I understand people get pissed. But as stated before, and having seen the new runes system, I think the stat system will be replaced with something just as fun. However, until that "thing" is announced, It really itches to manually assign attribute points.
Yet, why did they do this? Jay, said it is to prevent people to break their character. Yet they have confirmed respecs? And how about that "recommended" button that put points like the auto system will? I don't think he is honest, because the argument why they implement this do not make much sense. There is better ways to prevent people to screw this up!
I would buy the argument of skill balance. I noticed that some skills enhance damage output based on your stat. That sort of skill would be broken if we could manually place attribute points.
It would be just like D2:
Str/Dex for items
Vita is not your best buy anymore, ignore!
Everything else into Willpower.
So now you have a Wizard with say 350 Willpower. A lvl 15 Empowered Magic enhances the damage bonus by say 50% Damage, and then you have like 10 other passives to beef up damage.
Glass cannon builds galore.
