1e also gave xp awards for GP and magic items earned, as well as optional bonus RP experience awards."...but Lancelot, your approach means that I'll need obscene amounts of XP to get to 3rd level wizard!" Sure, but you needed them in 1e as well. At the same time your elven F/MU/T was hitting 2nd level in wizard (7,500 XP, split three ways), the party druid was already 4th or 5th level.
But yes, 5e is about as fighter/wizard-y as just about anyone needs to be. :3
