Galio's VGU would have felt more appropriate for Malphite
Please, consider what I am saying. It is largely OPINION
When someone says Gargoyle, what do you think of? I think of tanky little gremlins who are quite immobile, but quite damaging.
When someone says Mountain, what do you think of? A scary giant being who avalanches and crushes everything.
At this point in time, I think we could swap the two. I'm not hating anything, I just think the two are mixed up, or at least, thematically overlapping.
