But ... every MMO has that imbalance doesn't it? Take the really huge MMO's for example such as WoW ... there are the players who spend 100's of hours, repeat raids almost every day, repeat Instances over and over again ... they have the BEST gear, they have the BEST combinations of skills, they have the BEST knowledge of the game Meta and they have set up their characters to the BEST Min-Max possible.
Then there are those who can only play 6 hours a week or less... they maybe manage two Instances a week, hardly ever participate in raids... they have some good gear but they'd never manage to last more than a few seconds against the highest level players even though they are the same character level.
Is this the games fault? Do WoW players complain the game is broken in the same way Division players seem to? Or .... is this a lack of knowledge about how the game runs or what the game needs for highest level gameplay.
Would you expect to immediately blitz through LoL then complete in E-sport tournaments?
Players are making the MISTAKE of thinking that just because you are level 30 and you have a high average Gear Score that .. suddenly you'll be as invincible as that player who 1) runs with a regular crew, 2) spends hours min-maxing and studying the game meta.
So far, in my opinion, the imbalance is between the players who know what this game is actually about and those who think its pretty much just another console shooter with some minor RPG elements. It isn't.... the RPG side is hugely deep and complex and I will counter that it not just about the best loot....its equally about how you spend the time balancing your character build, spending time actually not doing missions but in the character skills screen moving stuff about.
