I think it would help the game to add more endgame content and I think rebirthing idea is awesome but a bit flawed. Some races get whole new armor sets, while others like AT's who are already 30/30 over Tit, just because 45/45 over tit after RB2 - This is an easy solve with a couple new armor sets going up to 145 with current system. Mithril / Adamantite? Whatever lol

But I am suggesting a new system

Instead of a flat increase across the board of +10 / +5, it could be +10% Stats/skills from the base and you can Rb infinite times.

Flat Increase per Rb
Max Rb1 Rb2 Rb3 Rb4
30 33 36 39 42
45 50 54 59 63
60 66 72 78 84
75 83 90 98 105
90 99 108 117 126
105 116 126 137 147
120 132 144 156 168

Compounding increase per Rb:
Max Rb1 Rb2 Rb3 Rb4
30 33 36 40 44
45 50 54 60 66
60 66 73 80 88
75 83 91 100 110
90 99 109 120 132
105 116 127 140 154
120 132 145 160 176

etc.

Of course this would call for a duplication of pents (think nightmare/hell in Diablo), maybe Rb pents but instead of private grolms starting, they're like Earl or Warlord grolms.

Basically I'm asking for the game to be endless and unbeatable. Mod cap would have to be eliminated and beating Rb Pents should take something like a flat Rb 100 or compounding Rb 25ish - This may an argument for flat increase and not compounding lol.

Also I saw a suggestion to give some quality of life changes to each race which could maybe be chosen at each Rb instead of stats, or maybe gifted at first Rb? I think the poor AT should have a base 10 meditate from the start

AT - Meditate
Hara - Stealth
Warrior - Warcry
Sorc - GC?
Seyan - Another arch skill or Blind or Warcry?

Etc
