That's painting with a pretty broad brush, isn't it? Or even a roller!
If you're building a model kit that has the correct scale ground clearance, lowering it because it "looks better" that way to you is a subjective thing, not a problem with the kit's accuracy. I mean, that's like saying pretty much any model looks better painted metalflake red. Or any model looks better with big aftermarket wheels.
All subjective, nothing to do with the kit's basic accuracy... assuming it is accurate.
