3) Create some way to earn rebirth xp back. Having players with 100m+ in taxes
is lame, and if people enjoy the game via trying new things they shouldn't be
penalized that hard
You probably meant reinc exp. I have to say I disagree with you on this point.
Reinc should have a cost. Also, there's been much talk about motivating people
to stay in the same reinc for a longer period of time.
I think the main reasons why people have started talking about "how to gain
exp spent in reinc tax back" is that it became visible, and hence concrete, in
"show experience". I bet people would start asking for potions and quests and
other various ways to regain exp that is lost due to death, if it became
visible in the same way.
