Summoner's Rift Lane Phase Meta

The main reason has been (in the past) the protection of the mid laner. It used to be mages who didn't have solid escapes. Now with more assassins (and the high amount of mobility) that reason is kinda void. The main reason you don't see it now, teams don't want to end up putting their assassin in a 1v2 losing some farm.

But I agree, the idea of a roaming support from the mid lane is amazing. I try to get people to do it all the time. It would allow for a LOT of jungle invades/defenses.

A few reasons.

1. Bot is closer to dragon, which is important early.

2. Bot, as a lane, is longer than mid. This gives the ADC time to farm and scale up, compared to mid which usually has the first lost turret.

3. So the Mage/Assassin in mid can roam and get kills, as well as be available for the jungler if there's invades.

4. Mid is closer to the blue buff, and blue normally gets passed to the Mage/Assassin.

5. Mid is also close to Raptors/Wraiths, so they can farm them if they need to.

6. Mid is a short lane, so Mages with little mobility can easily escape with a Flash if they need to, as opposed to the greater distances in bot.
