Massive structures that are an eyesore on the landscape are way too common. There is often no incentive to work through mods. No mods are integrated together to make it feel like a cohesive experience. Lots of cool vanilla plus mods, lots of bloat garbage. It has cool mods in it, but it also has so much crap mcreator mods that it makes it feel like the modpack maker didn't even test them before putting them into the pack.
The thing is it just feels so lazy to me.
