Photoshop: Disable pen/brush opacity vertical slider (Please Adobe!)

I always use the Pen alt+shift+horizontal slide to increase/decrease my brush size. I do not know when this was introduced, but when making a vertical movement changes the brush opacity (something I prefer to have in the brush settings instead).
This has been driving me insane for the quite some time now. Is it possible to disable this feature, I have not found a way yet...If not,  please Adobe can you add this? (I see others have reported the same frustration over this as well) 
This problem causes my brush to go down to 99% or 98% etc all the time when I want an opaque brush, and suddenly I notice the layer I painted isn't fully opaque (and you cannot instantly see that the opacity is at 99%). This is in many circumstances very problematic, especially when doing very graphical work - and it should be optional to have this feature on or off.

Date this function of Methuselah, it should under no circumstances be changed! It is simply best to control your hand to move the tip that horizontally and not the two axes at the same time! Or maybe change the sensitivity of your graphic tablet.

My tablet is tweaked perfectly for my use. and the sensitivity is good. But moving the hand 1 pixel up or down when I want to change my brush is very easily done by mistake, especially on a 4K Cintiq Pro tablet. How can you mean that I should degrade my hardware to accommodate a badly implemented feature which I don't use?
It should be possible to give the user the option to active both axis or not.

Ah than certainties... I don't have to degrade, but to maybe improve your settings.

It has nothing to do with my settings. Have you tried painting with a Cintiq Pro 24?  THe sensitivity is because the the pen has high accuracy and the screen is 4K. To move the pen 1 pixel up or down require almost no movement. And 1 pixel up or down you cannot notice you are doing, and suddenly you paint with 99% opacity instead of 100% withouth knowing. How can I change tablet settings for this? It has nothing to do with pressure sensitivity.

It wasnt a problem before I got the Cintiq Pro 4K, because it is more accurate and when I change brush size often when painting it so happens the opacity changes. I only wish I could disable the opacity direction since I don't need it and it only causes problems.  (dunno if this is possible through userprefs.txt or something)
