Yes, but stuff shouldt tf-above next tier, like normal gear should only TF to max of 920 and hc to 945.
For the moment, mythic loot is for most of it NOT worth the effort. And yes, a lot of people raid for loot, some say they raid for "boss kills", but they get happy when they get that 950TF+ item.
Id like for em to either do TFing as i stated earlier, or have mythic loot be able to TF higher than non-mythic, say lfr/norm/hc cap is still 955, but mytic loot could TF to 965-970.
