People only play game like wow to get character progression. What I am saying is that delves is probably what they need to drain anyone who isnt a diehard wow pvp player away from wow pvp. And eventually wow pvp population is gona be so small, you always fight the same people again and again, the que going to be insane and eventually it dies. This wouldnt happen this expansion, because delves isnt a mature pillar, but it might happen next expansion if this trend continues. Remember wow pvp took a major hit in legion when they introduced mythic plus and template? I could be wrong, but I doudt it
