I feel like the first camps of a game should get a nerf or SOMETHING. It's too often that I lose 1-3 minions worth of XP because my jg needs a long leash, OR if they connect a minute late and can't get get a leash, then they're behind for a while.
The whole concept of leashes is dumb. A jungler should be able to take their own jungle camps without needing help, especially if it could put the laners behind. (The first 1-3 minions' XP is a big power gap early levels). And I just think leashes should be abolished in one way or another.
EDIT: Many people are saying leashes aren't neccessary. Try not leashing in your next game. See if your jg will
A) Never gank your lane or help you at all
