A +1 modifier in everything is pretty much the worst way to go. To say that by trying to do everything you'll be good at nothing is an understatement. You'll be weak at everything, failing a ton of rolls and when something does land it will do very little. Forget about trying to play every class at the same time, it's not going to work or be good. Specialize at a couple of things and stick to those. A high damage dealing tank barbarian, a powerful wizard with a lot of utility spells, a high damage warlock with the charisma to twist the minds of everyone around, etc. Trying to chase this omniclass build is a fool's errand.
You misunderstand. I believe hybridizing the three surviving spellcasters is probably my best option (cleric-druid, bard-sorcerer, wizard). I, however, both want to know the best of the three classes, and the abomination for the meme. What is the best distribution of the chosen one's levels? I can't throw something like a half caster or a fighter in there, that might create something actually good. The fireball paladin may live in my heart as the funniest of all choices, but that's against the spirit of creating a mostly caster.
