To clarify, having you alts as your companion (as op stated) and leveling/gearing them all the while is game breaking , and not to mention it would obliterate Blizzard’s time played metric requirement. Leveling two characters for the time of one? Not a chance.
It wouldn’t really be a stretch at this point imo. Blizzard realizes that folks are getting burnt with leveling alts, but they also realize some folks don’t enjoy the mission board. Letting folks send alts out for these missions for experience just seems like a good way to have more folks utilize the mission board and hate it a bit less due to being useful outside gold missions.
In my mind, there would be a caveat to utilizing your alts on mission board missions. That caveat being that they’re not accessible while out and about.
The other side of me would like it if Blizzard made world quests synced with the mission board. Send your alt to help out in Darkshore? You can either let it complete passively via mission board or do it on the alt itself for increased xp.
Give people both. They have been working on the bodyguard AI. They started this with the guys back in MoP where you kill a certain amount of creatures to level them up. Then they introduced that gnome in Legion from Nessingwary that you train to hunt, now they’ve gone all in with Naz’jatar with three bodyguard options that level up via daily quests.
Some people will always hate bodyguards so the old fashion way + new open world world quests will be for them.
There is a concern in terms of old dungeon participation. If folks are just leveling their alts via bodyguard in current content, then participation in lower level dungeons will decrease.
If we are leveling alts in current content, it would be fun to reflect that they’re level 10 in a 120 zone. They’re pulling everything around them. Repeatedly dying. Chaos haha.
