I am sure I am not alone in saying that the bought past life feats are becomming harder and harder to take with the introduction of EDs because so many have pre req feats.
What I propose is allow a TR the ability to use a free feat selection at level 3 to obtain a past life feat. I think this would alleviate most of the issues with feat starved builds to obtain feats they so rightfully earned. Additionally I believe a 14th life toon should have earned an addional free feat slot at lvl 3 so they can fit their even more deserved completionist feat.
This suggestion will certainly not unbalance the game but in its current state, however it may provide enough incentive for a player to want to TR or achieve completionist. Afterall the most appealing aspect of DDO is that after you grind out your gear and cap your toon, there is still a way to make it better. Unless you have done all the above plus levelled 40 lives :P.
