Lack of End Game Content

[Avraym]

The tome currency works though and there 's not really a need to change it, the cap is rather artificial but it does it's job to pad out the content

I disagree. You can easily get Rokan's Goetia full set in a day - even in 5.0... that sure didn't feel like it was padding out content.

Phantasmagoria tomes are a different story with the cap and smaller gains - but it still feels lacklustre and too easy to obtain (lets remember that a lot of 470 gear BiS is Phantasmagoria).

I'd prefer if tomes were rewarded for greater achievements, rather than capped and hidden behind unchallenging content in an attempt to drag things out by nature.
