Leaving penalty

The leaving penalty is way too strict. You only get 10 seconds to return to a match in comp if you leave too early in the game I think that's a little harsh. Not only that, but I left a game early after winning it said "match complete" and I left and lost 50 sr points and 10 min penalty and I didn't even get a chance to get back in. All because I didn't wait for "VICTORY". Its ridiculous.
