What About a Line of Scrimmage?

I heard a caster in game 2 of SKT vs Misfits say "line of scrimmage" in regards to teams facing off against each other prior to minions spawning and it gave me an idea. What if there was a season of League - or even just a test thing on PBE - where there was a line drawn down the middle of the river extending from bot to top where, for the first 5 minutes of the game, anyone who crossed this line on either side was instantly 100-0 dead? (Line would be down the middle of river, bisecting the map in twain.)

It would be a meta that heavily favored farming to late game in mid-to-high elo and in all elos, it would give huge priority to tank (and probably hook) supports. It'd be interesting to see what people would do in lane if all they could do was shove their lane past the midpoint and couldn't harass enemies under their turret or roam prior to like 5 minutes.

This would also make freezing the lane on your side that much more effective because the person on the other side of the lane couldn't walk up for the first few minutes (and jg couldn't break the freeze). This would force people to learn to not shove their wave instantly (which BTW would probably shove poor Aurelion Sol - and most other roaming mid laners who want to shove and wander - out of popularity, but they could learn to be patient for a good 5 or so minutes and THEN roam. It'd just be delaying their opportunities to roam effectively (though they could also roam on their side of the river).

It might also require a change to the drake pit as blue side would have an unfair early advantage (perhaps moving the dragon itself out to like the center of the river with no enclosures around him. Hell, the drake could even take flight with enough nearby champions and do fiery strafing runs down river before settling back in his roost in the center of the river. (Scuttle would either be immune to this, removed from the game entirely, there could be two scuttle crabs per side of the river (4 in total), or scuttle could be instakilled by dragon strafing runs and the last team that touched it got the scuttle vision buff.) The brush in the center of bottom side river could be replaced (and/or scooched a little more bot-side) with a roost for the dragon to perch on.

It's just an idea. Obviously it might require changes made to creep equilibrium (buffing their health, armor, etc.). I just thought that the whole line of scrimmage thing needed to be said. Discuss.
