Nope, because everyone has the same exotic drop chance you do. A new Exotic drop rate was implemented for -everyone- not just those that didn't buy Forsaken. As far as it being 20 weeks and you're just now getting to level 20, that just means you've not been playing the game much. It's easy to level playing normally. As far as needing to buy the DLCs to progress further, that's also not 'pay to win'. Paying to win is being able to augment your character directly using money for content you're already a part of. Things like Iron Banner and the like are live events, meaning updated content, so if you decide you don't wish to have full access to that content, then you will be left behind. You are no longer part of 'current' content, meaning people who choose to pay for the DLCs that include all that content are, in fact, just keeping pace; they're not improving themselves by buying the DLC, they're gaining access to now-current content. You, if you choose not to have the DLC, are simply choosing to not have access to the full allotment of features that are available to you. If you want all the benefits of owning DLC, then you need to buy the DLC. Destiny 2 and its DLC release program is not Pay to Win, it's Pay to Play Current Content. The max level bump and power level equipment granted by the DLCs are DLC content and current content, and all Live Events are current content. It's a moving bar.

This doesn’t make since. 20 weeks of play time and you should have multiple characters at the vanilla D2 cap of 305 at least
