How long is top lane compared to bot lane? Top lane feels longer.

Exact same distance Camera angle just makes bot look smaller

The map is pretty much mirrored, so you have the same bushes and resources in the same places on different sides of the map. So for example, you have a top and a bot tri-bush.

It would seem like top is longer than bot because the fact that bot is all ranged champions and top is melee range a good chunk of the time

I have to agree with the OP, lets change it and combine top and bottom lane into one, shrink the river, cut jungle camps in half, have just a rift herald (no dragons, no baron) with one red buff on top, a scuttle on bottom, map goes left to right or vice versa and so map isnt stale like original add events like scuttle crab racing, king of hill, team 5 vs 5 with 3 lives etc etc.

We could also add a tower to jungles and ranked to it as well and to ensure games aren't too long add an event around 20 mins where nexus' walk out to middle and fight each other.
