Never worth. Puts your jungler disgustingly behind, and also puts you the laner behind.
Why?
Jungler will not get level one off first camp and is now at 50-75 percent health, still level one and has to clear his next camp on his own, this puts him easily 1 minute behind in pace compared to the enemy jungler sometimes more.
You as the laner- You had to finish the blue buff yourself, and probably took a few autos from the blue buff, and you are now late to get into lane, you missed out on creep experience and the opportunity to pressure the enemy laner. They will now have a exp, a minion lead, and a pressure lead on you. Even if you are the support it is not worth for you are asking the adc to be by themselves for dangerous critical moments of the level one trades.
