Horrible quote from the "Sign On San Diego" write-up of the re-branding here:

Thompson said the old MWC logo was “confusing” and “very busy” with the word “West” dwarfed underneath the word “Mountain” and a mountain range. The league's old slogan -- "above the rest" -- also was a nod to member teams that played at high altitude. By contrast, the new logo gives equal placement to the “Mountain” and “West,” reflecting the addition of western schools Hawaii and Fresno State. It also looks the same upside down or right-side up.

“The old logo was very mountain-centric,” SDSU President Stephen Weber said. “This gives equal billing to west.”
And bad news about what it costs:

Thompson said the rebranding cost roughly $250,000, including the logo and media campaign.

“We’re going to put it everywhere,” Thompson said of the logo. That includes uniforms and playing surfaces.
