Please bring back Bonus IP for parties

It was such a good reason to have a full team of 5 and a great incentive to earn extra IP. I have played this game for quite awhile now, several years in fact and I only own about half of the champion pool. Now I know that you can buy the champions and a few I have, but I prefer to spend my money on skins. The added bonus IP was great because I was able to unlock 4 or 5 champions within a week. I feel like a lot of people have the same issue and would love the added IP. PLEASE RIOT BRING THIS BACK.
