Onslaught solves ranked problems then creates new ones
In my opinion it shouldn't be the competitive version of world of tanks, onslaught light is great, make credits at tier 8 in short form battles where tanks have special abilities and power ups around the map.
As a competitive gamemode of world of tanks it falls flat on its face. its far too different from actual world of tanks and can feel like a completely different game. Ranked certainly wasn't perfect but at least the gameplay felt like world of tanks, it just happened at a time where the kranvagn meta was there and that sucked, also the chevron system sucked, pitted you against your team mates as well as the enemy team
Take the points system from onslaught and the gameplay of ranked and boom i think its better, but hey I'm just an idiot on reddit wtf do I know
