Do you expect to find the imga and sloads in the wilds of Tamriel

oh hell yeh, gotta love some beast murder for boosting

Imga, yes. From memory they inhabit Valenwood, so it would be odd to have them missing. Of course, judging by how Zenimax handled Khajiit, they could very well be missing ...
Sload, no. I don't think they'd get a very warm welcome in Tamriel.
