I think this has been discussed before, but I can't remember what they said about the topic. Id bet Baz would know but can't tag him lol.
I really hope they have it made so that if you are grouping with somebody significantly higher than you, then you get no xp or rewards of any kind.
Currently, I've been dabbling in WoW classic and there is a huge game breaking issue of "boosting." To shortly explain what boosting is (not talking about buying from cash shop), is when you are lvl 10/20 w/e and you have a higher level toon, lvl 60....invite you to a group and then go into a dungeon (or anywhere) and then very quickly kill the entire dungeon and then rinse and repeat. Meanwhile the lower level toon gets MASSIVE xp and tons of loot in just 1 run. There are literally instances of killing an entire dungeon within a SINGLE pull.
By doing this, it completely devestates the lower end game. I have been standing outside of 3 different dungeons for 3 days just spamming LFG and /who and messaging people to run dungeons but nobody is wiling becaue they are just getting boosted. The server is healthy and strongly populated. There is even a very respectable population at low levels. But its useless because everybody just hides in dungeons and boost. Essentially bypassing the ENTIRE game until lvl 55 or so.
It has gotten to the point that I just simply log off the game and I'm pretty close to just uninstalling it.
VR, you MUST put in some type of mechanic that if I'm grouped with another player that is 6, or 8, or 10+ levels higher than me then I don't get credit for it. If you do this, you need to also make a way for people to play together though. A mentoring system of sorts where the lvl 60 can mentor down to my level and have his stats more respectable to my level range, so we can still play together.
Its also important for quest too. So many times in other games theres an epic quest to kill this epic mob for this epic item and I work hard for it and build a group specifically for this mob etc etc. And then theres a guy that is 6 lvls below me and just got credit for killing the mob because his buddy 40 levels higher just 1 shot it for him.
Makes NO sense at all.
