A simple change to the map to solve alot of top lanes problems.
If the brushes on top lane brought you into a small pocket of jungle. Alot of top lanes problems will be solved. The major problems are:
- ranged champions completely destroy melee champions until teamfights.
- if you are counterpicked you dont get any option to do anything other than sit under turret and hope your opponent pushes.
- there isnt nearly enough impact on the game if you gank top.
Why would you gank top at this point? Simple. Either adcs start going top for the free gold, meaning top laners; whom can often solo dragon, are left bot, making top laners affect the dragon. Or top lane has so much gold at this point if you dont deal with them you will have to face a titan. Or simply securing the jungle farm is incentive to gank them. Trust me, it matters much more in the mid game if top laners have gold instead of adcs. Adcs only become stronger than top laners at a much later rate.
with comet I guess; 
if he gets the jump on them) which can close that gap vs a ranged champ lvl 1 without losing 1/3 to 1/2 hp and then they have a chance to win if the enemy plays it badly.
