As someone who kept pulling until I got Zhorak this whole escapade leaves me with a very bad feeling. I wanted to build an ice blast team for S2,so I kept pulling until I got Zhorak (I already got Shinah, ice blast epics and rares before). If I knew he was bugged I wouldn't have spent all the helio dice. I would have opened them in another banner. This way I am stuck with a falsely advertised bad legendary and with no helio dice.
To make things worse, it's impossible to prove any of this. I guess you could check the logs of my pulls,but not sure if this means anything. And even if it could be proven, what then?
Does the development team understand that half baked solutions like this are basically discouraging people from actually buying helio dice and spending money on your game?
EDIT: After my complaint I was contacted by @still drum who looked into the issue, and rightfully pointed out that Zhorak skill description was updated on the day before I obtained him. Therefore, its was my fault not checking the patch notes. So, even though the issue was not resolved in my favor, I have to say I am very pleased that SG team are taking time to listen and act upon the complaints. This personal approach doesn't exist in all games, but its very important for us players to feel we are being heard. So big props to @still drum and her team!
