I am a support main and have barely any hours on the ratguy, but just going against him I can totally feel that he needs a buff, or just something to make him viable again.

Even as LW I win most duels if i am not so stupid to follow him into a small room, because his squar-ish hitbox makes it really easy to land shots. Only really cracked rats actually give me a hard time, but at this time it feels you have to put in 3000% effort to just be as good as a soldier or ashe.

And then on top of it rat gets countered so easily it is not even fun anymore

so I will pray for you guys that you can actually 2-shot-combo a lot of heroes again to at least have somewhat of a niche
