I believe this game needs to consider a rebalancing of the current raid difficulties available in order to allow for a much more robust and flexible viability of gameplay for players with a range of roster characters, that allows for greater diversity and viability for those that want to push beyond the currently too low soft cap of 1500, whereby top level players are circumventing by parking their mains at 1500 only and leveling up to 6x 1460 or 1475 characters at the maximum efficiency cost-effectiveness.
I think it would vastly improve the overall health of the game to enable players to choose more effectively what range of roster levels they want to achieve which yields the same net result in terms of gold output to a certain general extent.
Given that the current cap item level is 1575, I believe the game is badly balanced and imposing a too low of a soft cap which punishes players to level anywhere beyond the 1500 item level. It too harshly and rigidly forces and imposed limit to the player and requiring them to level up many alts to a much lower threshold giving them little room to progress alternative to the set base standard of only a single character at 1500 and rest all maxing out to 1460 where the minimum requirement of Hard mode sits.
There should be additional scaling difficulties beyond hard, for example, Normal, Hard, Nightmare, Hell, and finally, Inferno (but not the equalized mode that we know), which caps out at 1550 or 1560 instead. They just give additional materials and gold which scales to be to an extent that considers the trade-offs and differences similarly as if someone played on 5-6 alts all 1460 in the current system running all Hard modes.
This would make it less inefficient and cost-effectively punishing for players to focus on only a single character and reach all the way up to the prescribed cap of 1575. However, mainly this would accommodate a range of roster levels beyond 1500 that can be achieved and net a balanced result. Upon which, you would then add some kind of limit or cap to how many characters could run the higher difficulties beyond hard mode, while also restricting how many characters run hard mode IF you have a character that can run the higher difficulties.
For example, if you have one character that is 1550, you would only be able to run maybe 2 additional characters on hard modes and earn gold rewards, and you would only be able to run a max of one character at the 1550 level. This is at the core, simply a QoL balancing update to the difficulty scaling system, which is already in place, giving more room for players to have freedom of choice of playing differently sized rosters of accompanying levels greater than 1500. Many players, myself included, simply cannot given their real life situation, spend every entire week, playing on 6+ different characters, this allows them to still be nominally cost-efficient without in anyway sacrificing the need to have to level up a roster of characters.
With this update, players can choose some in between roster composition, say one main that pushed to one or two levels higher difficulty but just 2 or 3 alts at hard difficulty they play per week. Comparative to 6 alts maxed out playing it would still be a much higher overall reward.
You would only increase the rewards of the difficulties by a small margin only but at least it’s not like utterly capped out at 1460 where if you only have a single character at 1560 you’d get a measly 1/6th of the potential rewards vs someone that had 6 characters each running the max difficulty. This doesn’t make any sense.
It would not warrant making it so it would FULL EFFICIENY viable to play ONLY one character, than all 6 characters at a high level. It would be a compensational type of balancing. You would likely have some in-between composition, with the trade-off to benefit drastically drop-off at a purely single character player, this is very important to note, versus someone that maybe has one main and 3 alts, but now they can have say 1x 1560 main, 1x 1520 alt, 1x 1500 alt, which all run higher than hard difficulties, and it would put them somewhere in-between someone who relatively speaking at the same-ish leveling output have 1x 1500 main, and 5x 1460 alts, or another example of say 1x 1520 main, 1x 1500, 4x 1460, etc…
Effectively, if you ONLY wanted to play a single character, you would have a drastically less efficient output at the highest difficulty, but not a complete waste of being literally 1/6th the rewards as someone who spent the same resources as you did to get one character to 1560 and instead 5x 1460, this is the borderline basis for this rebalancing update.
