I'd really hope something like this would never happen. That would basically stagnantly conform league of legends to this meta for the foreseeable future.
i disagree, i hope this happens [if only at least for draft pick/ranked] because things would go much, much smoother. I think just better wording for top and mid need to be established. As an example, me as a support player, can go wherever the hell i want. It is normally strongest if the support is with the AD carry. i some cases though [like ifmy AD is being a hopeless cunt] ill go and support mid, or top. In this scenario i still have my role, but go wherever the hell I please.
even then with this system it lets more reasonable people come in and play [most of the time, no system is 100% If you wanted to "change the meta" you likely would need full agreement from your team anyway, or you likely would still have someone flame and troll you throughout the game. If anything this new system, if it ever would get implemented [Riot pls], would allow more for meta shift, as more reasonable people would likely be in queue together.
