The change to Heavy has two sides. The biggest benefactors are the small species who now have an important weapon restriction lifted. On the other side of the coin are the gishes who substitute a caster stat for melee attacks, your Blade Warlocks and Battle Smith Artificers. They now have to devote a little more to Str to have access to the big toys. Which is not an especially onerous ask, but it is an ask.
Hmm, there's a thought. With the new requirement on Heavy, and depending on what Mastery trait you want, would that finally be a use-case for fighting 2H with a Versatile weapon? Or is it still the case that if you're not going full on Heavy weapon, you're better off with the shield AC?
