Occasionally when i hold a corner i get killed by an enemy that i couldnt see is there something wrong with my posistioning? an instance i can recall was playing lamps on bind and the oponent shooting me from the left part of short.

Over the last few weeks I feel that I have noticed that whenever I play as sage my heals on teammates don't count as assists if they get kills after the heal... Has anyone else noticed something like this? Is it happening to skye as well?
