I got burnt out years ago from the constant grind of doing the same end game stuff for each alt. When TR came into the game I came back and found enjoyment again constantly going from lvl1-20 and TR. I won't be able to do that now unless I stock up heavily before update 20 on True Hearts of Wood using my epic tokens. As they don't stack I refuse to have my character filled with hearts for future lives that far in advance.
Turbine, you have multiple ways of doing things already ingame. Yes, it's sloppy, but leave us our epic token turn in and possibly even add iconic reincarnation wood and epic reincarnation wood for epic tokens in the twelve also.
If this change comes about you might as well remove house cannith challenges. All the people I know only do cannith challenges to change them into epic tokens for hearts of wood.
