thanks for the heads up . might get this as a backup mod . Edit Well I just bought the ipv d 3 kit , 2 ud zephyrus tanks , an Aromamizer v 2 RDTA tank for $ 40 shipped . Yay black friday deals ! <| sep |> In a way I agree . But if I go back and think about it only WoD and Legion have this problem . WoD with the Garrison and Legion with class hallsartifact weapons . The other expansions all either introduced systems that got carried forward or improved systems that were already there . And I like that approach better . I ' m not a fan of these one and done features either because they feel meaningless the second the new expansion comes out . I ' m okay with smaller things like the farm in Mists or the choose your building leveling system in WoD , but these huge systems that then get left behind are a waste imo and feel like busy work .
