i know that is no main problem etc. i know that 90% kids have big orgasm when they get next prestige... but for me its annoying, i have 20 now and some of kids quitts duels before even it starts, others have to comment that (high prestige)... i be glad for option that enable/disable showing prestige...
Well, it does serve as a sort of indicator of skill. Not actual skill, but time spent on a hero should mean that the player has learned something about playing it. I say should since I've stomped quite a few rep10+ heroes, and been stomped by people who hasn't reached rep1 yet. I see where you're coming from, and it can be frustrating, i guess this is why so many are screaming for a ranked mode, so their actual skill is shown and not just time played.
In the end it's all down to the other players, some will always quit without trying.
