In pubs, specially, spectre still can absolutely destroy common line-ups, and can become an unstoppable force in the hands of a good player, while also being hard to counter. Just keep playing her, at unranked games, to get a better grip of the hero

How so? What is her role? again, excuse my ignorance, but thank you for helping me out :)

We can't really know how Icefrog choses which heroes to mess with. At first we think that he buffs heroes that are picked but too weak, and nerfs heroes that are looking too strong. But I really don't understand why he buffs LC and sniper, while leaving heroes like Razor, Visage and Treant untouched for example.

I love razor and tend to do well as him. If he got a buff, I'd be a happy camper!
