The Azeroth is a pretty decent RDTA. It has good flavor and decent functionality.
I despise the clap decks as I use simple coils and they seem to be more frustrating than the old 3 post style. I do get it though, in terms of using fancy coils.
From the deck down the Azeroth is basically the same as the limitless. Side filling, easy wicking, and a glass tank on the bottom.
The top section has tons of airflow but it's very difficult to adjust. The airflow ring is tight and thin. While there is some texture to I assume assist with adjusting, I find myself just pulling it off to adjust. The wide bore tip is pretty nice but mine barely stays in. A wisp of air knocks it out of the cap.
When it works though it works rather well. Flavor is pretty solid and it has that Limitless signature ease of use with filling and wicking. I'll always recommend the Limitless but I would recommend this over the Mage Combo RDTA any day.
