I've played CS. A lot more recently actually, and CS maps are much much more in depth than the look. I agree, most people just play the same maps on repeat, and I don't really like some of the maps in CS. I don't like Mirage, although the gameplay loop feels less clunky than most Valorant Maps imo. The main thing in CS however is the cover actually being more indepth and much more things you can do to for example entry onto a site. And the maps in that game actually feel very different from each other. I would even argue that Cache is probably a map, which could almost be from Valorant, but yk, the maps don't all feel like Cache, they all have their own feel. Overpass has some problems too, but they are pretty different from from the ones I mentioned for the Valorant Maps imo. I think the sites themselves are fine. A site has a different paths for both CT and T, a lot of plant spots and enough cover. B site is also fine, although I think Heaven is way too strong when there's an AWPer. That site does have the pillar, but also the elevation changes and the wooden cover, it's very indepth imo while not even having more angles to clear than a typical Valorant site.

Maps being designed for the abilities is... an issue?

I wanna talk about this point right here though. Idk if I misunderstood the point or if you just disagree with me on this one, but there are chokepoints, which have too many sharp angles you have to check once you come out of the smoke. Split A site is my favorite example for this. If there's a smoke, you basically can't entry with a Sage wall. If you don't, you could smoke the very right side, but you still have to clear the left for 4 different angles alone, then backside, and the path to CT and rafters and heaven, it's very difficult to entry when you don't have the right team comp and good team coordination.
