Change for Sigma?

So, after some time playing on the beta, I noticed that OW2 feels more like a giant deathmatch than an actual objective-based match, due to the removal of one tank. To fix it, we must come to the origin of the problem.

I can be wrong, but I think it’s shields. Now, Orisa rework has obviously been a success. Why not give the same treatment to characters who can bear it ?

Like Sigma, for instance, who could have his kinetic grasp work like Terminus’ siphon from Paladins : a vortex-like thingy that works with a gauge (like matrix) wich absorbs damage to give various bonuses (health, or shields, or reduced cooldown, you name it !).

This way we could keep the tankiness, go back to 6 v 6, whithout having the whole game spent damaging shields ! Let me know what you think.
