I've got 4, but only 3 are going to get upgraded (one is an Unholy ring from before I ditched that spec). But I do use all 3 regularly based on situation and will continue to do so.
I don't know if I'm relieved or annoyed that we can't farm them to infinity by spamming mythic+, since we were planning to go hard this week. We want the +15 and it's the ezmode (for us) sanguine/overflowing right now. The funny thing is our feral druid was itching to try for a +15 last night because we had a +14 nelth's key to attempt...it was skittish/bolstering/fortified aka the dead cat druid combo. And yes I've suggested he hold off for a few seconds on pulls like you've said, he doesn't listen.
At least I didn't get my fifth legendary before today, my friend got his fourth a couple days ago so he got boned. I've gotta be close by now, even considering I've wound down my playtime quite a bit I still did heroic/mythic raiding, karazhan, emissaries and several 10-13 mythic+ runs a week. Over two months that has to be a good amount of 'bad luck protection' built up. Gimme them Sindragosa pants.
Wonder how far we'll get this week. I've got 9 bonus rolls saved and I need to spend 3, I'd prefer to spend them on heroic but Nighthold seems pretty long and we only raid two nights for 3-ish hours. We do outgear normal nighthold significantly, at least. I could pug something but I don't hate myself that much.
