My dream Reaper Mode.
No trees, RP's
Increased chance to get named gear, bonuses on said gear or rare items (augments, filigrees, etc..)
With great risk should come greater reward.
Other than the loot and XP/levels nothing else should better you odd from reaper level to reaper level.
This would also mean those looking to run reaper, only have the past lives advantage over the first lifer.
This would be a much narrower gap and would more likely encourage grouping of the two player types.
There would be little need to shun a first lifer or see it as them bringing down the group because they do not have a couple hundred RP's to pump them up.
Not saying this is a dream that everyone has to agree with, only that it would be interesting.
Maybe do a no reaper tree guild. Not sure how you could really enforce it and you would not have the increase chance to item drops to make reaper worth doing in place of the RXP reward component.
