Why limit team invites?

I'm just curious if anyone can clarify this for me, I have a ranked 3's team. We got it to plat 3. Now I the original members whom I played with it to that goal, aren't on as much as before. So I'm looking for new members to play with. But I can only invite people like every week or so. And it makes it hard to find a correct 2 other people who can function well together. I can find one person but then say a 3rd isn't good enough, so I want to remove him and add someone else. But I can't do it for a certain amount of time. Why exactly does this invite limiter exist in teams? I saw a red post saying that there was a way to abuse the system, but I honestly don't see how you could abuse the system by constantly being able to invite people to your team. With the new rule in place that a member needs 10 wins to gain the rewards of the team, you can't just spam invites to everyone so they all get the rewards. So with your new rule in place riot I believe you can remove the invite limiter. Reason being is that, if someone isn't skilled enough to get 10 wins with the team. Them being on it won't affect there actual status. TL:DR - Why do teams have a invite limit? - With the new requirement of people to have 10 wins on a team to get the rewards I think you can remove the limiter.
