D&D 5E Color me baffled - attack bonus in Next

[Li Shenron]

I see it as a chance to play a Gandof like spell caster who carries a long-sword and knows how to use it!!!

Yes, but in fact I think this is exactly the sort of character that the designers want to support, and in general I believe it's a good thing. They just need to make sure that the options are balanced enough so that it doesn't enable the "one build to rule them all".
