Re: Wattson needs buffed. Period.
I recently posted this on another thread, but it would be good if her fences were only activated once an enemy passes through them. Once activated, they would stay active for ~10 seconds. It would give her fences the element of surprise that they desperately need. More players will accidentally cross the fence, and this would make Wraiths passive, Bloodhounds scan, Mirages decoys and Crypto's drone more important for trap detection.
I think her ult should stay active on her back and stay active for a short time, while increasing its shield charging effectiveness so that it can fully charge a level 3-4 shield in one charge. This would stop the ult from being destroyed immediately, but would make Wattson more of a target while it's active.
