I think it’s time to really look at sigma, and how the high elo meta is currently Orisa, Sigma. Overwatch is an fps, and playing against double barrier is eliminating the aspect of being able to aim at someone and shoot. Sigma can eliminate the threat of a flanker or sniper, by simply constantly moving the barrier to a location that shuts down the threat. We all want to see more dps heros being played, I’m sure on the dev team too! And for that there are some adjustments that need to be made. I think rock stun needs a greater timer. The barrier needs a rework, perhaps lower hp, smaller, a bigger timer? Perhaps it’s not exactly a barrier? Maybe it’s a 50% damage reduction field of some kind that can help negate an ult. Off tank with out a full barrier would be a good place for Sigma. He has a D.va eat, and a stun already. Giving him a full kit of main tank really off balances things. The damage of main fire probably also needs to be slightly adjusted, to about the dps of orisa main fire.
OP has 1 min 28 seconds play time on sigma
Oh my god I thought you where joking! 
Isnt the meta Orisa/D.va and Orisa/Hog?
Double shield is just a pubstomping ladder comp lol
its also funny OP complains about damage when blizz is already putting that change in the PTR
but to address the OP: Get 10 hours of play time on sigma and then get back to us. You have no clue of all the issues that he has with the rest of his kit.
Orisa is good with everyone. She and her facilitator Ana need adjustments long before we look at Sigma again.
Orisa’s barrier should be more like Rein’s and Sigma’s when it comes to regaining health. Give it more health to compensate, let her reposition it more frequently, and maybe let it regenerate without being lowered. I just single-handedly saved the meta.
So it’s really a single barrier that she recalls and deploys? That would be interesting to see!
Oh i think it’s good. I hate those annoyings dps (widow, genji), and i am happy that now they are getting more punishment for their mistakes. and Sigma is not OP, he is just able to annoy our favourite spider (oh no, now i need to flank, rly? i thought widow is about staying in one position very far away from everyone (without any threat) and one shot), and weeabo that can’t deflect pathetic rock. (while genji can deflect graviton) (how is this possible for nano-blade ninja?)
i feel no regret for these two. sigma is not op, he has strong counters and other issues. leave grandpa alone.
