Ye obviously what I say is just my own opinion - I thought it’s so obvious that doesn’t worth mentioning.
Don’t know about Global Board of Game Development, but Legendary things should look Legendary not Common - this is pure common sense. New maps use typical layout, color schemes, ideas (wow a circle with rune symbols, wow a mountain with stalagmits, how cool and innovative). In fact, that basic map with swimming pool and frozen dragon inside, on top of a mountain with chinese-like decorations all around and a foggy riverside view on the background looks much more legendary, than a plain purple piece of rock with pink circle and one stalagmit. Pretty sure first one took much more time and passion to create, too, since how many details it has compared to second
But, as I already said before, for people like u who play more than a year, new maps will be obviously cool, just because fresh and no matter high or low quality level - that’s how it always works.
