As someone who likes to make experimental builds and test them out I occasionally run into the issue of a build that just isn't viable. It looks good on paper and if it ever got to end game it might still work out nicely, but in practice leveling it up just stops being fun at a certain point. This typically causes me to "brick wall" and I either TR a character I'm not ready to or just move onto playing something else.
What I would like to see is an item added to the game (preferably not a purely DDO store item) that is another type of reincarnation heart, call it a corrupted heart, broken heart, whatever and all it serves to do is it acts as a true life reset. Usable at any level, it will allow you to immediately completely reroll this character as if you had true reincarnated. IF something like this is implemented and it does wind up being a DDO store item it should at least be cheaper than the other TR hearts as you gain no benefit, it is simply a life reset.
-you will retain all previous reincarnation feats
-retain access to all the gear etc via TR cache (may need to be emptied like current TRs, guessing the mechanics will be required to be the same)
-lose all currently gained levels and reroll at 1 (or 15 if rolling into an iconic)
-can change race, sex, alignment, and class just as if you had done a true reincarnate
-do not gain a new TR feat for the current life (the one being rerolled)
-if a first or second life also do not gain the new point builds
Honestly I have run into situations where I would have loved to have something like this on several occasions, invariably a year or so later I wind up coming back to that character and just suffering through and getting to TR level and immediately TRing, but it isn't fun and usually gets either prefaced or shortly followed by a hiatus from the game.
