Is the intended role of Caitlyn's traps being accurately reflected in the game?

IMO, the problem is that supports usually have multiple forms of cc that they can chain together to create pretty long immobilization times for enemies that they can catch. Blitzcrank can grab and follow it up by a knockup. Nautilus can hook and stun with an auto then slow with his e. Leona can root with her full combo for quite a while. Morgana's q alone is devastatingly long. It seems contrary to Caitlyn's kit that she should be able to place a trap underneath one of these support combos to extend the chain of cc for an even longer amount of time. If Riot simply made the traps 1 second longer to set it would have almost zero bearing on her ability to create a pre-emptive zoning area but would eliminate combo-ing the ADC to comical levels.
