If you've read my guides before, but haven't revisited in a while, just know that my Medusa and Freya Arena guides have been converted into guides for all modes (pretty much).
Both have ADC versions with full writeups, and Freya also has a Jungler version. Arena builds have also been revised.
With solid, existing guides by other people for Odin, Loki and Ravana, I do not have any current plans to convert those.
As for good ol' Bacchus, he doesn't appear to have any other current guides, but he's not really the most common pick in Conquest, so I'm hesitant to put forth the effort to convert that one.
So anyway, just a heads up on my current guide-making status. I don't have any plans on new ones, as it's a lot of work just maintaining the ones I have, but I have no problems reading and providing feedback on others' guides. Just send me a PM to get my attention.
