Premades in Hero League

As someone who still plays and enjoys this game i thinks its very bad to have 5 premades play against 5 random players in hero league and this is on going thing its just keep happening, just imagine 5 people on call comunicating all the calls and everything and playing agaisnt 5 people who never played with each other its so unfair just return back storm league and hero league or make like obligation if u are 5 premades you need to be match into 5 premades anyone who played any sort of moba understands how big of advantage this is, i hope you can at least fix that ASAP.
