Games need a focus, otherwise developers are spread too thin, that is just the way it is. It's not as if I defending this exploit.
So you are stopping your players from using Haste and/or Quicken Spell to cast 2 levelled spells in a turn too? Because I consider this to be a larger balance upset compared to PnP.
Yes. It's seen as not 5e compatible. I cast haste on the Tank/Warrior personally, then cast Evocation spells starting on my next turn while keeping myself protected from the enemy. Also we don't do barrelmancy.
I don't see how you can see that as a bigger exploit than the one I mentioned but you are entitled to your opinion. A Sorcerer with every spell in the game that they can apply metamagic to is 100% broken. They can then get haste from a wizard scroll and twin it with metamagic, all with 1 level in Wizard.
