I played with Kamwah yesterday too. First game the other team had 2 disconnects so we left. Then we was doing ok, then suddenly Kamwah disappeared. I waited for a while but things got a bit hard and I realised Kam not coming back so I left. Waited a while longer then had to go myself.
But for the short time we did play it was fun. Can't remember which hero Kam had, but when we was in same lane he took most of the last kills. Was particularly hard to get last hits with ursa. But I enjoyed playing with ursa. The claw is nice to chomp down an hero quickly. Hero's like razor don't have a special that does that much damage. Razor's one might do more damage overall by area, but ursa concentrates to one target and does more damage to it enabling one to get more kills easily
