The state of top in soloqueue

So, lately i was wondering what is the "value" of toplane. For example, when bot is lost, so the enemy adc (probably tristana) has more farm, more kills, simply more gold than ours. Then they have an incredible power, because adc's are a lot more dominant than other roles. Plus, they have dragon control, and probably they can spread their pressure out to even midlane, and so on and so forth. But if toplane is losing at the moment, nothing is at risk. It's not a huge drawback when your toplaner dies, because it's not that big of a loss as a midlaner or an adc. As a toplaner myself, giving one or two kills to the enemy laner means nothing if he/she isnt some extremely snowbally champion. (for example irelia, darius or riven) Every single lane has a big impact when given the right amount of xp or gold, except toplane. A fed adc can carry the whole game. A fed apc has incredible teamfight presence. However, a fed tank or fighter usually gets kited or just outranged. Most of these problems are found in items and imbalanced champions, but it just bugs me that i usually win my lane, i come down to mid to have some skirmishes or teamfights, and i'm barely worth as much as our midlaner who had a fine lane, but still has less farm than me. Riot stated in patch 4.7 that toplane is like an island, it has no noticable impact on the game, and since then, (if we dont count the jarvan changes that patch) They didnt change anything about toplane. Maybe except nerf some overpowered champions. I'm slightly disappointed that there is actually a good idea to change the feeling of the game, and riot puts it in the "not important and never will be" box.
