I'm still confused over this issue. So let's list the reasons for raising preflop.

-1- Isolation/buying button.
-2- Information
-3- Value
-4- Balance (Shania..)

-4- seems irrelevant, since online opps are usually unaware. At higher stakes this might become an issue (>400NL).

-2- is valuable, although you don't want a call from someone with position.

I'm not sure about -1-, although buying position is very valuable of course. Isolation.. Well, playing AJ/KQ HU seems more EV to me than playing it 4-ways unraised. I lack skill/knowledge/experience though..

Not sure about -3-.
