the difference is that chamber had a free op, eco pocket guardian, and could teleport halfway across the map (and was good in pro play) whereas clove is a ranked warrior that has a low impact decay, a semi-useful heal which doesnt get impact 80% of the time and a self res that most players run away from. the reason clove frags in ranked is that you can place down your smokes rly quickly and then just hold ur gun out instead of flashing or placing stars (viper can do the same thing as clove on icebox tho)
