So I guess I'll explain my thinking a bit more. There are four main things which I can see someone doing control wise. The first of these would be to start a slow-push in a side lane and then start making pressure mid. This allows for your team to rotate to the slow-pushing lane and quickly grab that 2nd tier turret. The issue with this is that it is easy for someone to simply clear the slow-pushing wave while still putting up a solid 4 man defense mid. The second strategy is to go for a 4-1 split push. The issue with this particular technique is that it almost always gets stopped very quickly unless the lane had already pushed up to the tower. Of course the upside to this technique is that it forces movement away from mid-lane allowing for the rest of your team to try to force something mid. The third technique is to do a 1-3-1 split push, but this leaves the 3 man squad very vulnerable to getting 5 manned. Lastly, there's the 5 man push down mid, but this rarely results in a tower as the enemy needs to merely set up a 4-1 split or a 5 man defense to stop it in it's tracks. Are there any other general strategies I can employ, or tactical things I could do to increase the success rate of these different strategies.
(unofficial fourth/fifth is vision and jungle objective control, but these are, while necessary, outside the scope of what I'm asking)
