I am not sure if this was an accident or put in as a solution for first 30 days of Kunark and accidentally left in when superseded by 30-day exp ban, but.... scroll exp is 50% of pre-Kunark amounts.
I tested on 51 DEF ENC. 1 yellow took 19 scrolls before Kunark, but now it takes 40.

I tested on 41 HFL DRU. 1 yellow took 5 scrolls before Kunark, but now it takes 10.

I also talked to Artelius Longwood. He had similar results of 50% less experience at levels 53/54 on HUM RNG.
