I'm not mh moderator - I'll post anyway
1) He missed like 20 sunstrikes this game
2) They had wards (did you even check a replay) pitlord was buying them.
3) That situation you provided was just luck - he knew sniper couldn't get far enough, it was completely random. Even more random since sniper was moving like mad and didn't follow any expected trajectory, so since sunstrike is a delay based spell - he just got lucky sniper walked into it. If you are talking about previous kill on sniper check 2)
Maphack moderator will check this game anyway, but I'm 100% sure your request will be denied.
