To answer your question , it hurts the carrot on 25 . It hurts the other who do not want to do more grind .
As with the previous post not all people want to grind and tr all the time so as not to be gimped .
The status as it is now if you don't have 3 past lives at least you are consider by some people a gimp . Let me explain , a caster with no past lives cannot finger of death on epic lob so he is considered a bad player so he is not invited . With adding a new carrot on lvl 25 you creating an incentive for the 1% of the people who like grinding and discouraging the rest 99% .This is ddo now with tr mechanism .
With Epic destinies is ok as you can be at end game content all the time . So still enjoy the end game and not grind the same lowbie quests for a long time .
