Funny thing, because personally I was thinking about opposite, having party option "no past lives, no reaper tree, no ship buffs, no tomes - just knowledge, player skill and gear".
R1 with overpowered passives is just too easy (aka boring for some) especially when you have whole party of uber characters instead of doing solo.
I can understand if you are talking about higher reaper, but taking R1 in a group is just super easy mode.
If you have uber character, then what is a problem running R1 solo?
What is the difference between going solo and having party of weak characters on R1?
Just handle it like you would go solo if you think others in your party do not contribute on that such "super hard" difficulty.
I was always thinking that uber characters should do higher reaper.
You just want super easy xp for another past life and do not care about other things in the game like social or challenge.
I play since 2010 and prefer reaper difficulty without extra passives (no past lives, no reaper tree, no ship buffs, no tomes), because I like challenge.
I play that way with my friend in private party, we do not want to be carry by anyone and we would be happy to have some new players with us no matter their contribution, but you say that players who prefer challenge should be penalized, right?
