Hehe, well it's a free game so why not give it a try?
If it's what you really want then you ow it to yourself, otherwise the idea will be stuck in your head for 5 more years.
Newsflash, this just in... *smacks himself on the forehead* ...can't believe I didn't think about this sooner!
How about the Eldritch Knight from the DMG?
It's your idea all worked out!
TFrom its discription: "The Eldritch Knight can cast fireball at it's foes and then charge them with sword drawn." Nice, yes?
It has a d6 hitdice but it's spellcasting continues as normal -1 level. Not counting the multiclass level(s) you already took.
Taken into account his pre requirements, I'd make it so:
Level 1: Fighter (profficient with all martial weapons, good hitdice)
Level 2-6: Wizard (the sorc has lower level spell and with the -2 level you already have makes it too weak)
Level 7+: Eldritch Knight (1th level no spell level increase only fighter, then it levels normally but with fighterisch bonusses)
This may be a very nice and powerfull charcter!
Think a fighter who buffs himself before the fight. In the fight he starts with a fireball and then comes in melee.
...I may even try it myself.
