It's unrealistic that you'd face any # of goblins as an 8th level wizard (XP equivalent to a 4th or 5th level party).

Well, if the XP during the EA was done off of a split instead of the way it is done now, you potentially would. Its possible to get to level 4 before the goblin camp already, quite easy in fact.

Yes, because I have no issues killing the 2 minotaurs in the Underdark at level 4 on a Wizard, Ranger or Warlock solo, without abusing stealth, during the EA as is.

Now, encounter balance is difficult, so you might be right. This is something that only detailed encounter testing can reveal.

I would be surprised if it is impossible, considering it would be awarding more XP than is currently awarded now and its already possible.
