I'm not sure if posts like this are allowed here, but I just want to share my painful experience with the Titan crystal...
So far I have opened 7 Titan crystal, each time filled with hope and excitement. This hope however has been misplaced, as my pulls so far have been:
Morbius dupe, Havok, Luke Cage, Sersi, Silver Sable, Silver Sable again and now Nova
Everytime I hope to at least get a new champ so I can play around with them a bit, but the one time I do get one, it's the worst champ of the year and then dupe them right after

At this point I'd rather open a basic 7* crystal than the Titan
I'd love to hear about your experiences with the Titan crystal, good and bad!
