As from the title, this game would be a struggle for casual's. Folks out there look at builds from content creators that suit their play style. They may have even snagged a pic on their phone of a passive skill setup for the Gates of Fate. With it's near symmetrical node mapping layout (especially the middle ring) from section to section it maybe tough for some folks to understand the ring alignments (would be awesome if each ring had an edge ring with the name of the tree like "EOS", etc.). That, coupled with the fact that you cannot alt-tab in game, would make it tough for many casuals to do as they would normally do with other titles within this genre. I would start with the alt-tab first :)
