Literally just occurred to me today, but doesn’t the current incarnation of valor actively encourage boosting?
Observation
Because KSM now unlocks a very desirable game feature, the pressure on players to get it has increased. Even players with no interest in doing 15s still benefit from having KSM. In fact, the lower your preferred level of content, the more having KSM benefits you.
Hypothesis
Removing the KSM requirement from valor would decrease boosting, potentially dropping it below 9.0 levels. As a side effect, it would decrease the number of players wearing 226 vault items while never having personally learned how to clear a 14+ key.
Meanwhile it would provide casual players access to an upgrade system without having to find a million gold for a KSM boost. Some will buy boosts anyway. Many won’t, if character progression is available to them.
Cynical Thought
Reduced boosting would reduce the amount of tokens people buy, which is why valor is how it is.
Long Read
Casual Sam doesn’t enjoy high M+ keys or raids above LFR. We don’t know why, and we don’t need to know why, we just need to understand that there are a lot of players who feel the same as Sam.
They’ve maxed out their covenant gear, and are sitting, predictably, at ilvl 197. Where does Sam go now?
Oh, 9.0.5 brought valor! Sam can keep upgrading without having to go above the M+4s they feel comfortable in!
Except it’s capped at ilvl 200, because Casual Sam doesn’t want to go above a +4.
Now, Sam has known about boosting for a long time, but never bothered. Get a timed +15, get an item out of the vault, yadda yadda. But Sam would rather do stuff their own way, on their own time, under their own power - if they can. They have some friends, who also prefer to just stick to low, easy dungeons. They just like an excuse to hang out.
If only valor upgrades were accessible, they’d have character progression… Sure, it would take 40 dungeon runs to get this weapon up to 220, but Sam knows they will do that eventually. There’s no rush, they just want to know that they can. But unlocking 220 requires the KSM achievement.
Which can be bought.
So by buying a KSM boost (or even a 10s boost), Sam can now get access to the valor system, allowing them to plug away (slowly), doing Callings and M+4 with their friends, and slowly upgrade their gear.
Oh, and they happen to end up with some 210s and a big vault or two from the boosts. Which is a bigger impact on their gear than valor alone would ever have had.
