I've also had a pretty good time with full harrier's providing alac, regen, fury and low prot uptime. Since we can't really keep all 3 shades up at the same time I've been using just 1 or 2 for barrier/alac generation and saving the rest for rezzing when needed. I feel like they might be wanting to move shades to a more utility option but I'm just speculating after playing it for a while.
