Do you think Sigma is killing the game?

I think that he is maybe a bit too powerful but the changes in the PTR and too much and destroy him.

reducing his biotic grasp cooldown by 4 seconds from 14 to 10 is actually huge. I played him on the latest patch last night and it's crazy how often you can eat a ton of damage and generate shields for yourself. I think overall the shield nerf was a good balance move by blizzard, hopefully killing the shield meta but still keeping sigma viable and in a good place for your team's main tank.

i think sigma is a really cool guy and should be cool
