Hey Grim,
Chiming in to say, thank you for giving us new stuff. Always good to see new things come about and effort being put in certain areas. I won't touch on too much of the other buffs, I'll touch on Trendy.
As would I. Bear in mind, people leveled and played the game just fine without some of these buffs for a great many years.
I do think you need to drop the whole DOA thing though. It might be to you, but not everyone.

People did play the game just fine with Commons before. Those were the times without CoA/CoD, your Epic Forges/Crafts, and your Smashing Hammers and your other high level buffs. That was well over a decade ago. I still remember how big of a change it was when SH175 became a thing - the way we leveled and the gear completely changed, and has remembered somewhat the same since.
We live in times where the game is much further advanced, the way we play has evolved to a much finer degree, and resources are much more vast and readily available. Resources meaning Legendary/Crystal/Epic gear, and the variety of buffs + the (high) degree and ease of access.
That said. I do agree that there are people who play the game differently should have a place, and that creativity should be rewarded. But like others have mentioned, Common items haven't really... been a thing for a while.
BUT you have a great opportunity here to make something special. Truly, truly special. But that would require a crazy adjustment to the #s in Trendy. As in, make that potion a high high high level buff OR adjust the % number in the buff to be higher. Something that could single-handedly shift the way we use Common items and how strong they are. Shake things up a little, you know?
If chaos ensues, there's always tuning it back down.
Love you Grimmy ~ SS
