Please don't invade unless your jungler wants to

It's getting really annoying when our support Blitzcrank wants to run into the enemy jungle and miss 5 hooks and burn his summs and force his team to come burn summs to come save him. And then our jungler gets really behind, and often don't even get a leash (good luck ...)

Just stop. It's one thing to ask "hey guys, wanna invade? I can start hook and TF can start W, our Xin can even start E for the gap closer." It is an entirely different thing to just say "invading" and force your team to either let you feed first blood or burn all their summs saving your dumb ass.

Just, please, at least ask your team if they want to invade.
