Uhm… Well… That’s kinda obvious. The whole premise of it is based on the fact that too much convenience is your enemy, not your friend.
But ok, you know what, it’s not like anyone saying anything definitive now is going to matter. So just wait for TBC Classic. If they do bring back rated seasons in that, and bring back the Elo rated system they used back then with the arena teams and tabards and names and so on, then you’ll see how few people will be going back to looking for players to play with every time they want to do arenas like so many people do now in retail.
Social glue matters.
But at the same time that is a little off-topic in this thread, so about the topic of this thread then as explained in the post where I linked to it, it’s that by making it more strenuous to boost, then it’ll actively discourage it. Which that “penalty system” would help accomplish.
Or as you put it: “It sounds like a chore.” … Obviously. Which is the whole point.
At the same time you motivate people to play together more regularly instead of so many defaulting back to the group finder every time, as well as not really making much of a difference for the people who already plays together regularly, and it doesn’t “lock” you with a hard limit into only playing with a few people which was a common complaint back during the days with the arena teams.
It just makes people feel it’s more worth to play with the same people thanks to the natural path of investing in them, as well as making it take a longer time to boost which actively discourages boosting, which would help reduce the amount of customers for it.
You can’t keep your cake after eating it. It’s because of the overly convenient options in place that the group finder is a mess, and boosting being as easy as it is, that it has become like this.
You could discourage boosting more by separating PvP gear and PvE gear like in WoD (best system except for Trashran, thus far), but that only takes care of the PvE people who are only looking for ilvl. It wouldn’t affect the people buying boosts for titles or mounts whatsoever, and the group finder would still be the same mess as now.
As mentioned already, boosting can never be prevented fully without hardcore policing oversight of their own game on an individual level. But the suggestion above at least discourages it a bit more for every potential customer, instead of only discouraging the PvE people, while at the same time making it a better option to play regularly with the same people instead of going back to the group finder every. single. time. people want to play which in turn makes it harder to find people since people become more and more distrustful after recurring negative experiences, which in turn leads to all of the lying which makes people more distrustful, which leads to people wanting “better and better” players to invite just to avoid losing their rating.
It becomes a death spiral, leading to where the game is now, and it will only continue to get worse.
“The grass is always greener on the other side”, while people think it’s always easier to find someone “better” to play with than to improve together whenever the smallest problem comes up with the one(s) you’ve already found.
