[Unanswered]  secret layer base nerf?

i've noticed with the layer bases Grand, Rock, and Bushin that the gt chips' teeth seem to click looser than on an attack base. could this be TT's way of nerfing them or do you think i just have bad molds?
Personally, how the majority’s of the meta for the past 2 seasons revolve do around more Balance, Defensive, and Stamina combos rather than nightmare Longinus, Cho Z Valkyrie, and a few more. Safe to say that I saw probably why.
It's how they're trying to prevent Stamina Types from dominating again. It's a feature on all Defense and Stamina Bases and has been pointed out by others earlier
