Druids currently do not receive weapon damage from weapon enchants and weightstones. The reasoning for this has seemingly been that it was not in the original vanilla and as such would constitute a “change” contrary to the #nochanges policy of world of warcraft classic.
I would like to point out that this whole basis is dubious. Something like a slight adjustment to damage like this is not exactly obvious and easy to actually test or even perceive, and seemingly the only proof that it was not like this in vanilla are random WoWhead comments and the like. However if you’d like to take the word of random wowhead comments, there should also be Black Lotus in Dire Maul:East according to several seperate comments, yet this is not presently in the game simply because, it would seem unlikely according to some preconceived notion.
Now I would think it indeed seems unlikely that these weapon damage enchants would not carry over to feral forms as the counterweight, another weapon modifier has indeed been confirmed to work for feral forms. Ultimately I think it would depend on the coding of the game, do they engender a new instance of the weapon with another value of damage, or do they simply add the damage to your Characters final stat calculation… The fact that counterweights work would confirm that it’s the latter.
Now one thing is that weapon procs do not work for feral forms, but this was likely deliberately put in place since such procs from enchants and the “On hit” effect intented to certain weapons would indeed be freakishly overpowered if transferred to a 1.0 second speed weapon from a 3.5-ish
