Hello,
I think it's excellent the Thieving Skillcape has an effect now (for those who don't know, it now reduced the chance of being caught while pickpocketing), however as you typically want to use the Ardougne Cloak for the bonus experience I'm finding that the new skillcape effect is not that much help.
I could understand if this idea isn't looked upon favorably as maybe it's better to have to choose between one or the other, but I wondered if perhaps the thieving cape could count as an Ardougne cloak as well.
If there were concerns over people then not buying the Ardougne cloak then perhaps you would have to use one on the other to merge them or something of the like?
