Not a junk generalization. People complained about visual clutter in the beta. Saying they wished we could have simple clean looking maps. Just an observation I made.
It's just my opinion but I like the clean forge blocks. It's better for forge in general. There were some forge maps in Reach and 4 that looked great. But that's because those were forged with aesthetics in mind and very few instances of pieces melding together. However most community maps are designed gameplay and don't regard how the textures and art on different pieces work together.
With clean pieces everything melds together great.
I much prefer the halo 5 headlong to this atrocity
The actual ground textures on these maps are pretty rough though.
