double legendary and 2x legendary/mythic are events I would say it's worth pulling shards, I haven't pulled a legendary from Ancients in ages now, not since the last double lego event, when was that? February? I pulled Dutchess + Wukong
Man ive been talking to clanmates since the last 1+1 ancients event and I barely missed it but I'm at 200 on mercy so at most 20 shards and I'll get 2 leggos. I've saved 69 since the last event so I'm hoping for at least 1 gnut
