personally for fighters anything below level 5 looks partially trained to me.Who decides what a 0-level character is? 1-2 levels have little to no abilities or options and contrary to many corpse-thirsty DMs, squishy as hell. The only thing not making them 0-level is the fact that they call it 1-2, chopping two useful levels off the 20 level game to do so.
ie the lowest tier looks like an apprentice tier.
