Zarya sym nerfs were necessary

Zarya literally gets her charge from ppl shooting at her bubbles and lots of ppl do it w/o letting up and sym gets hers from shields. Both of these can be stopped by not shooting bubble and switching to a tank with no shield. The reason other tanks are in a bad spot is exactly what happens all the time, ppl refuse to change to counter they nerf them to all hell and then we are stuck with some new meta. Now we are stuck with all these shields and they are removing the counters that were used. It’s like Blizzard just wants the same heroes used every single match And honestly don’t see a reason to keep all the other heroes if they just keep deciding to make changes to only make those ones viable.
