Abusive is when you start seeing 3 or 4 classes. A Ranger1/Barbarian1/Fightern is abusive IMHO.
I would say it depends on the situation. I'm sure you meant it without saying it, of course.
I have a character, a dwarf, who has 1 level in ranger, 1 level in barbarian, and his other levels in fighter and frenzied berserker. Abusive? I don't think so. To me, it fits his character.
1 level lf ranger for the favored enemy. I chose goblins, since this particular character hates goblins.
1 level of barbarian for raging. This character is a battlerager, and therefpre must be able to rage.
Levels in fighter, for combat training. Battleragers are good warriors.
Levels in Frenzied Berserkers, for rage power. If you look in 2nd edition, the battleragers were one of the best, if not the best, raging kits of all. Its abilities combined with barbarian abilities secure the character as a powerful rager.
The situation is pivotal.
