Again, very true, and I'd also bet that there were plenty of groups that were entirely console players so wouldn't have the option to even have a PC player with ACT check their numbers for them. However, if they're playing the kind of content where a tool like ACT is incredibly value added without it then that really just illustrates how unnecessary it is. It would still be very useful, I'm not arguing against that, I'm just saying if people can do it without the tool then that's just another reason the Devs wouldn't want or feel the need to make it natively supported.
