The "DM" should also generally keep an eye on game balance - and cater for those who care about core rule implementations. Rules provide structure and allow for game balance (and common sense) - lookup the definition of a game, and the rules are a core part of that.
Many, many people have asked for a RAW 5e implementation option (like Solasta showed can work). Many (all?) other computer D&D games have a 'core' setting. Just because some people are used to DMs who don't actually care about rules, doesn't mean that those of us who do enjoy carefully structured and balanced mechanics should simply be dismissed.
EA provided ample opportunity for issues to be pointed out with Larian's' interpretation of 5E - most of that was ignored...even though the game was meant be the 'definitive 5e' experience or some such quote from the early EA days. *I* bought into the EA on that basis, so while I enjoyed the game, there are mechanical aspects that make me roll my eyes in disbelief since they are exactly what I would expect a 13 year old DM to allow as being 'cool'. All this has been discussed to death in many threads.
So I tried it out and it is balanced. If you take 10 sorc levels and 2 of Wizard, while you get access to a level 6 spell slot you can't learn any level 6 spells on your sorc level ups, even if you took the Wizard classes at levels 2 & 3.
What you have to do therefore is still make INT your main stat for it to work, and that means losing all your speech skill bonuses.
Also I took evocation specialist and sculpt spells, but it didn't apply when I cast a fireball with sorc spell, only works on spells memorized under wizard
I didn't test if I could use metamagics with the wizard spells, my initial thought was you could, but based on sculpt spell not working for wizard spells, I don't think metamagics work for wizard spells, I'll test that now.
Actually I was incorrect, sculpt spells just didn't trigger while in camp, but it does work on sorc slots, and metamagics work on wizard slots.
But for a 2 wizard / 10 sorc to be able to use chain lightning & disintegrate, they have to make INT their primary stat not CHA, which tbf is still superior to a Wizard. Looks like I'll do that on Gale instead of on my MC.
And actually if I do it on Gale, I can't have Warcaster as companions need 2 ASIs to get 20 in casting stat so meh.
