My issue with Control Wards is very similar to my issue with Vision Wards with respect to wards and traps: instead of countering those objects organically, e.g. by detecting them at close ranges if they had Camouflage, players still have to use another item to remove them, which isn't great. On top of that, though, Control Wards have a spread of different effects, compared to the true sight of Vision Wards, which makes their optimal use a little less clear (why give them Camouflage detection specifically?). In the end, Control Wards are still mostly just better Stealth Wards that require a free inventory slot to use, and I would've preferred it if Riot had removed Vision Wards entirely and worked from there.
