For one, to each their own - I enjoy having to operate jobs differently depending on the level range. Having to repeat the same exact rotation regardless of level range once I reach max level would bore me to death more than having less buttons to leverage performance with.
For another, as many have said before me, the amount of effort and ressources required to actually design LevelSync-but-not-actually-Sync without any of these conditions happening:When the former is a thing, it may be subjectively more fun for some, but is generally biased towards new players in value. When the latter happens, the system is biased towards high level players because they have many more broken tools that cannot be affected by scaling.
- High Lv Player providing the same value with exponentially greater effort (= unhappy High Lv Player because unfair value:effort ratio)
- High Lv Player providing more exponentially greater value than Low Lv Player (= unhappy Low Lv Player because powercrept)
Lastly, assuming condition 1 happens and we try to make it fair - how do you even design a system, that dynamically adjusts damage values, potencies, defensive, offensive and restorative properties of each action just to keep the power level of say a Level 90 the same as a Lv50 player? What if the Lv50 levels up mid run? Does the damage of the Lv90 get unnerfed? What if we have a Lv90, 75, 62 and 50 player in one run? Do we scale around the Lv50 player or do we create an average between levels and scale it that way? What about enemy stats?
Those are all possibilities one needs to consider if they made toolkits available regardless of level for a fair system. This isn't the first time I explained it to someone and no matter of how "boring" a level range is for someone, it is not worth designing a system like this - the workload is astronomical and would span multiple expansions to get right, but at what cost?
If we want to ask for something, ask for them moving more skills down the list like DRK receiving Stalwart Soul now at Lv40 rather than Lv72. Make jobs less top-heavy in upgrades and more some things down and rescale content and / or potencies around that.
