Climbing On A Non-carry Role.

Hi everyone, I'm FatalOverload. I am currently Gold 3 on the NA server and this is discussion is something that I have been thinking about for a long time and I wanted to get some other peoples thoughts on the matter. So I am a Jungle/Support main and within those roles I typically play tankier champions rather than carry style champions. A problem that I run into on frequent occasion is that there will be many games when I'm playing something like Amumu in the jungle and I will be just for an example lets say 4-1-7 but my carries will be something along the lines of 2-8-3. Typically this will result in losing the game because my carries will get deleted and I'm left standing there tanky as hell but it doesn't matter because my carries fed the enemy carries. I ask myself what a pro would do in this situation and I have talked to some of my friends that are in high Plat and low Diamond and typically they have one of two answers which leave me very frustrated. They normally tell me learn a carry role OR just hope for better teammates next game. I feel like those are poor choices because honestly I despise carry roles, being incredibly squishy is just not my style, and as for the better teammates next game standpoint, I feel like that is simply rolling the dice and hoping, which is not an efficient way to climb. So ultimately it boils down to learn a carry role/champion in order to climb, which just seems unfair because I am typically good at tanks and rarely have a poor score, even when we lose. I believe that the rank system should be more reflective of the players performance and not the entire teams performance. Because as things stand, I believe that my friends are right and it is incredibly difficult to climb on anything other than a carry role/champion.
