Yep I agree with what you say, the game currently offers little to non-meta classes at 280 if they don’t have friends/guild to play with. But then the game isn’t like what most MMOs are, which the content only starts when the player reaches 280 (current peak). The game starts when the player creates the character and focuses on the journey towards the end. This is evident that most of the really good gears are split across all different levels, like cafrisun @lvl15, arde at lvl90, petamion at lvl130 etc. This is also why you see many classes and builds are great during the journey to 200. You can build almost anything and still be viable.
There said, there is no content at all after 232 (Cranto Coast). The game just abruptly stops there, what is released after that are just quick stop-gap measures that IMC did to give players something to play with while they prepare new content, but sadly it is still incomplete. This is something akin to what a number of AAA companies do too, they implement something quick first, then over a series of patches slowly add more content to bring the other classes/builds back up to par.
I’m just going to state an example here. D3 with its Greater Rifts, it was implemented and only the top builds can get to high GRs with it. Many complains back then, it is only through numerous patches and balancing then you can see other builds get to the state where it is now.
As per what many others have highlighted in numerous other similar threads, if the game rolls out a reset potion, it will worsen whatever little diversity we have now.
By human nature, players will often or not, pick the path of least resistance. Having a reset potion just give players more excuses not to run non-metas since they can reset to the most efficient build to do that job. Class pigeon-holing will be even more apparent, it is either reroll to wiz3ele3 or we won’t take you as a dpser (although now is still bad).
IMC should actually do more to balance up the classes though, understand the game is still in its infancy, so do hope they will actually balance up the classes to increase the diversity of the game.
