Caitlyn Tactics?

Ive been playing Caitlyn for like 6-7 games and i cannot figure out any effective niche. Im aware that her headshot+trap hs+net hs is a very effective 3 hit combo that can be easily setup with proper setup and a little cc from your support and has the potential to get a kill on either adc or support. however one thing i cant believe people arent talking about and wasnt in the patch notes is that her trap radius got much smaller.If you look at the radius before you set it in game and compare it to the ability example of her traps on the champion screen that hasnt been changed yet youll see that its much smaller. Its to the point people can walk around them in the bush or even if i try to hurridly put 3 down to block someone off there tends to be a patch they can walk through. Also the 1 second delay between trap placement makes it very hard to set them up before people just run past and often i panick to try and wall off a part of the jungle and i end up blocking off a non important area and the fight moves elsewhere. I saw someone say that its possible to put them down as you go to try and trap any melees that are on you but the delay to cast + the delay to arm is too easy to see coming and theyll just move around without wasting much time. Even if i try to wall of one side of the lane to try and secure my position it really feels like it doesnt make a difference im already in decent postion to where they wouldnt run at me anyway so the traps feel useless in that sense. Also feel very silly when i put down traps to setup an area that get pushed back only to see the enemy step all over them out of the long range while taking no damage. Im not saying shes weak and needs a buff i just feel very frustrated trying to learn this character against other adcs that have a much easier intuitive time just landing skillshots (jinx) or just knowing when to initiate (graves) i feel that on caitlyn given all these longer animations i really have to predict more than i ever have before and i have to do it perfect cause i dont have much hp my escape is now slower and if i dont take my oportunities early to get some advantage i feel like ive fallen too far behind to come back. even when i spectate some of these higher elo games with caitlyn shes always negative (not a universal truth im sure) but still not a feel good moment. At every turn every new build (even crit damage runes) i never feel any more confident, useful, or rewarded for the time ive put in. Please someone tell me what im doing wrong.
