I just ran "Wake me up" on EE with my 1st account and 2nd account.
Account 1 has the Greater Tome of Epic Learning and is level 30.
Account 2 does not and is level 29.
For both it was the 1st time this quest was completed in non-heroic diffculty.
Both died once and both received 77,775 exp.
I just read the description "this effect will have no effect for characters that are below level 20 and above level 29".
This feels wrong. Because when this tome was put up for sale the maximum level was 30.
Now you could be anal/splitting hairs and say legendary isn't epic.
However while there is no level 40 and no [Greater] Tome of Legendary Learning available it feels like a bug/oversight.
