Yea if there's no changes to notable stacking or the warcry nodes it'd probably be a real strong contender to start with. I had initially misread how taunt works so I was skipping those, cause it read like bosses (shaper etc) were taunt immune, but I guess they are only immune to aggro portion of it and the taunt still "works" to trigger intimidate with.
Only downside to league starting with it might be leveling as a marauder/berserker, as they tend to suck for a while, but I'm not even sure you really have to be a berserker. Could easily just use the clusters on champion and go reave or something.
