If the brick is unbalanced, then I suppose any telephoto lens has to be considered unbalanced as well. The 90/2 is nearly as big, and the 50-140 dwarfs the brick. For me, coming from a Nikon d810 with the 24-70/2.8 and the 70-200/4, and frequently with the 24/1.4, the brick on my X-T2 feels more like a much smaller and lighter version of the d810 with 24/1.4. I also tend to hold the lens regardless of its size because it's then placed optimally for manual focus tweaks anytime
I had the Fuji grip, but ultimately took it off because I found the half height section of the grip annoying. I replaced with a RRS plate, and don't miss the grip at all. I use a peak slide, anchored at left lug and right side of the bottom plate (which I also did when I had the Fuji grip), so the xt2 with brick (or any lens actually) rides the front of my hip facing down anyway.
i guess, for me, if it's unbalanced, it's a phenomenon that simply never affects my shooting and I never notice it.
