2010

First time I've heard of this.

The rework yes, helps, but the chances for spells were practically untouched (it seems only Castle bans were fixed, but I'm not sure).

Too lazy to dig through the TXTs, but the chances definitely started to differ and if you believe the calculations, then in SoD the chance for arrow is around 89%, while in TE it's around 82%... For some reason there was even a decrease :confused:
In Inferno slow now appears more often, since they have many banned level 2 spells, which increases the chance of slow. But overall idk. :D
