Wraith running through Wattson fences is Not ok.

There can only be one wraith per team so just kill her if she breaks through, simple.

Wattson is amazing in the right hands and if you main her like you say, than you should know she is best when already having a set up made for an area rather than attempting to do so when being chased, unless you are good are managing speed and placement that is. 

I love her and main her in rank because she can assure a win more often than other legends. She can cut off areas for enemies and if a wraith does manage to make a portal across for her teammates, you are bound to hear that and if you can't, that means you are far enough not to worry about it. 

Attempting to place fences while on the move is a dangerous game but can be done given you know where to place them already and how to cross them so that they stall the enemy without spending to much time. 

Wraith being able to phase through it is justifiable and fair. She can phase out of any damage, explosive, gunfire, and even circle dmg. This is pretty much like complaining that she can avoid Caustics gas traps if she phases through it. No real argument here besides wanting a buff for your favorite legend. 

So I didn’t read all the comments in this thread (cuz y’all have a lot to say) but I think I understand the problem that you’re having with Watson. Now if I understand correctly it’s the initial delay on setting up fences where for about a second between placing a fence and it becoming active is where people are running thru correct. I too have had this issue once I got used to it I just started placing them slightly further on my run because chances are if they’re just going to chase you they’ll get caught in it during the chase instead of at the door. As for the tournament/ranked, there’s a reason Wattson is still considered a ‘must pick’ by teams and it’s mainly due to meta, being able to have defense and, the main one, the management of enemy ordinance. As to the reason why you don’t see as many Caustics it has to do with the fact he’s not good at dealing with incoming nades / ults, and when barricading yourself somewhere with teammates the visual impairment and slow to not only your enemy but possibly a teammate can be a BIG factor in winning and losing a fight especially in a tournament. I wasn’t surprised to see as many Watson’s and pathfinders being played, I expected it. However, that doesn’t change the fact that for the most part her kit is lacking behind her squad mates and it’s even worse if you find yourselves in front of any enemy in game by yourself because there’s virtually nothing you can do but hope you have better aim and better shields 8/10 times you loose the battle and she’s an easy pickoff target for coordinated teams. 

@CRRAZYM3X1CANO There aren't many characters that can do much when forced into a one on one fight so that seems odd to say. She can't be much bigger than Lifeline and neither has any escape or tanking abilities.

@SilentChillBruh I'm torn on your issue. Complaining about a long time character's baseline ability doing exactly as it always does feels... ridiculous. When you think about it though multiple characters have a way to bypass her tactical themselves or bring their whole team. Octane can jump pad, Pathfinder can zip line or swing over, wraith can ghost through, gibraltar can interrupt it and I honestly don't know what happens when Mirage sends a clone through.

Still most defensive abilities have a weakness so I don't have any sympathy for Wattson.
