The ranking system is a great idea on paper but the way it is implemented sucks. It is also easy to manipulate.
Solo players will struggle to get above gold 3 when facing a team of 5 no matter the tier unless you are a very strong player but even then will most likely lose even if they get MVP as gears is very much a team based game.
I don’t think there is a real solution to fixing this but maybe ranked game mode for solo players only could be a possible solution.
Also remove the rewards for each tier so to stop (or at least reduce) boosting and manipulation of the system and keep it simple to match players of similar skill against each other.
Gear’s 4 is coming to the end of its life so we are stuck with a broken system. Let’s just hope TC have taken on board casual player’s comments and not just pro player’s comments for gears 5 so everyone will have a better experience
