Yes these talents are for people who are in progression raids and PvP. The fact that the OP said in a later post 'I don't want to have to make up for the badness of healers' screams out that he hasn't seen a progression raid when healers are undergeared/pushing it for the content. Its not being bad, its the numbers and off heals/ survivability talents can make get you from 5-6% wipes to downing the boss .
