Agree with @Anlbrd !
The point of Wattson is not to do damage with her fences, they are purely just a deterrent. Her effect on an enemy team is often a very effective psychological one. The other matter of fact is if the enemy is trying to shoot your fences in a push then they're not paying attention to you. Try pushing with Wattson when the enemy are trying to crack a hole in your defences, you can often take them completely by surprise.
here's a game of wattson, i couldnt use her shields out in the open, her passive is useless here and her ult would be useless too. all of her abilities here are useless i mean come on she needs some sort of buff for these types of situations;
ya maybe but there was a team of three just beside the building i was climbing up and they could have flanked me and i might not have been shot climbing the building to help my teammates because of the other team that might have flanked me fighting the sniper team down the road. faced with the proposition of fighting two teams alone or keeping my team alive i chose to try to keep them alive and got shot in the process.
i was squished between two enemy teams and also my team was dying that would have meant i was fighting alone, it was not good three ways.
if she had a gibraltar shield or bangalor smoke too i might have made it up the building.
you never know. this isnt a religious or scientific experience its a game and i think, if i ask maybe, maybe they might say ok, well buff wattson and shell kick * and take names and youll be happy. thats what i hope happens.
Wattson is similiar to Caustic, she is good for defense, not offense. She doesn't offense or escape ability.
In your situation, you set up defense in close area, ask your team mate to crawl there, let them come to your term, until they give up or move on.
If they kill your team mate, simply wait it out until they move on.
Note:
There's reason people doesn't thrist, they want down enemy as bait so their mate team mate come in a rush, like 911 call, in panic emergency mode and blew up all the strategy out of the window , simply rush in and die easily in the process.
I don't agree that Wattsons fences are useless. As mentioned before I think they just need to be tactically positioned to be effective, so the base cannot be shot.
In some scenarios this is easier said than done but then you just don't set it up there. Likewise to some legends the fences are not an obstacle (Wraith, Pathfinder etc) but then everything needs a counter. Going back to getting shot it's exactly the same as Caustics trap and if they are planted in the open they are shot just as easy, if not easier.
In regards to her ultimate you could argue it's not spectacular early/mid game but come end game and dealing with grenade spam it serves a purpose. That and the fact I've heard they are stackable so you could have 3 all charging your shields quicker makes it useful, not forgetting they charge instantly with the ultimate accelerant.
