I used to be a (lol I'm not going there) dics healer for PvP back in season 9 and 10, but than I could not be arsed to do it any more. Lately I've been picking up PvP again, but I went shadow instead. I've been upgrading my gear slowly and it came to the point where I need to start getting the set items, but here's the problem: right now I have 5/5 healing set and it works kinda fine, And I took a look at shadow 4p and I was underwhelmed to say the least. I mean 5% casting speed on the two rather underused spells? I'm not sure if it's even worth go get, since healing one has proven to be rather useful.
Any thoughts on this matter? Is there really any use to be gained form the shadow 4p set that I'm missing?
