When the changes come in like you said and they are well balanced, i feel that the top lane will change a lot and that ganks will really be a risk early on a jungler can take, but if he fails, he will fall behind.
A jungler will probably try to clear as fast as possible to reach lvl 4 and then go b and shop. then the first gank will probably happen. A lvl 2 gank that fails will probably force the jungler to stop around lvl 3 with the clearing and go b for the first time, while the other jungler got a lvl advantage and can go back around 10-15 sec more early.
I think all that sounds so awesome, cause it forces the jungelr to make more decisions (more important decisions) but will also reward him with a way better chance to carry and influence the game not only early, but also mid and late game without being a second support champ or lee sin.
