Gangplank Barrels Chain Travel Speed

Lets say I place a barrel in the bushes. I have it set up. I then place down another barrel and instantly shoot the hidden barrel connected to it. The time it takes the barrel explosion chain to happen especially if the chain is longer the barrel is EASILY defused by even one person. Just had yasuo defuse my barrels the entire game no matter how tricky I got with them he made it impossible to hit him with them. Its already extremely hard to place the barrels without them being killed its even harder when you can't chain them. The speed on the barrel chaining explosions needs to be like triple the speed it currently is.
