This may not be popular, but I feel like Pharah needs some work right now. Hit scans dominate OW, and the map ceilings are incredibly low. Pharah can’t even fly over buildings on most maps, which is ridiculous. That would give her an excellent advantage and cover, which she definitely needs.
The biggest change that would be impactful short term, though, would be a similar to Orisa and Cassidy’s ult—give her a damage reduction or major health boost when ulting since she is a stationary target.
