When?
We need to take it to the next level. Any form of boosting needs to be a punishable offense. It hurts all levels of ranked pvp.
This needs to be addressed immediately
How would you enforce it?
If a player is 1800+ with a 0 rating player. Not really hard to identify a carry. Or at least reward 0 rating to the low elo player. simple really.
That’s a passive way to stop Carries and all I got as far as fixing it
Ok so the boostee just needs to gain 1 rating to bypass this system?
He gains 0 if he wins with a teammate having a significantly higher elo
If you’re looking for an actual solution to reduce the already low amount of carries I think that removing or reducing the amount of power tied to rating would help. The amount of people buying help fell off a cliff coming into s2 when they made the pvp gear weaker in pve.
Soo…you can’t help friends set their characters up?
No, that’s a carry. Think outside of just you and your friends. It hurts the entire game to allow Carries to destroy low elo players
Restricting the pool of players that one can play with doesn’t sound like a great idea. I mean, the reason that we’re getting rid of faction barriers is to get away from this philosophy.
How would enforcing proper ranked groups restrict play?
Weak input bro
Low elo will always bump into a much, much better player from time to time.
I don’t know what that has to do with massive rating disparities and carries being too common
“I want to play with my friend but he’s too high rated for me to gain any rating. I guess I have to find someone else.”
Not really, considering MMORPGs live and die by their community and the ability to play with others.
Boosting isn’t going away anytime soon.
Again, very weak input. “It exists bro, get over it” is very very weak.
Also your “friend” wanting to play with you isn’t justification for carries being “ok” in ranked
Play skirmishes
They really aren’t, though, at least not anymore. I went into 2v2 a few days ago with a mixture of 220-233 gear from comp stomp expecting to get my teeth knocked out but most people were in similar stuff, along with the oddball pve guy with some keystone or heroic raid gear.
Make PvP gear more accessible, at least the honor stuff.
Maybe reduce power between conquest ranks, or remove entirely.
You’ve missed the mark. The issue isn’t gear.
Sure it is, because friends and community is core to the MMORPG genre. You may dislike this but it is the foundation upon which all content in the genre is created on.
I think you might be more interested in a non MMORPG experience.
I think you might be interested in skirmishes and another thread you can derail, bud
Nothing is stopping you from queuing skirmishes with your low elo friend. 
Future replies from you will not be read
There’s nothing stopping us from queueing rated either. Your idea would stop us, which is very antithetical to the MMORPG experience. Grouping with friends should be encouraged.
You can’t enforce a “boosting ban”. I don’t necessarily agree with your reasons for wanting to ban boosting either, which I will address now:
There are a lot of things that are “unfun” to play against. Should everything that people find unfun, which is highly subjective, be banned?
Same as above, there’s a lot of other things that “hurt low elo matches”.
Other games do other things, but why should WoW follow what other games do?
Reported for trolling
Actually boostings are normal through out the whole esport communities. You will find boosters in many other famous games also.
