Every other vendor in the game either allows a rank reset, or you can continue to earn engrams past the "max" rank. His rep and reward track work the same as Fynch or Nimbus, where you gradually unlock rewards but then "max out". But unlike them, you just stop earning engrams at the max rank? What is the point of that?
It's supposed to be a super rewarding game mode, but at some point the more you play it, the LESS rewards you earn? There's no point in doing his daily bounties after you hit max rank either.
is it disappointing meh,
I don't even think you need a fire team for this to reach level 50 at this point and you'll get 6 drops, unsure didn't count. Plus the extra coinage -10 for more at the chest. then you have the bounties that give you a chance at your god roll. then you have the next 50 run to complete that and get more.
so 2 hours to get 12+ chances
and then you can switch characters and do it all over again (if you run more than one)
so not getting more rep at Shaxx, not the end of the world. If it we're like Nimbus and you gained more rep to get the one extra chance = meh
