Wattson in a good place ?!

I was avoiding the line of questioning regarding my play history with Wattson because while she is my most popular character, whether or not I play her a lot is not even relevant, just like me getting the fence damage wrong is irrelevant. The fence damage was originally 10 and apparently at some recent point it was changed, so I'm not even "wrong". Half the time my fences get crossed they're from stragglers across the map so the damage doesn't even show up. You should know this.

As for your claim that teammates' projectiles aren't negated while within the pylon radius - that is laughably false. I just played several games where my teammates tried to save themselves by using tacticals but because they were next to my pylon, they just disappeared. Bangalore tried to smoke - GONE. Horizon tried to throw an anti-gravity well to escape a team that just rushed her - GONE. DEAD. Caustic tried to throw his ultimate into a window to cleave a whole team with the perfect opportunity to get an instant squad wipe - NEGATED. 

"i actually lost a game on Olympus this morning to a wattson who made a great fence play on my team and cutting us off from each other"

If a Wattson was able to "cut you off" from your team, then you weren't together in the first place. And I'm not sure how fences stopped you from getting a win. Unless you're playing in beginner noob lobbies where people have no idea what anything does, normally players just walk through the fences, eat the tickle damage and slow, and proceed as though nothing happened. So this sounds like a you failure.
