A couple dozen games with Morgana
Kills, Deaths and Assists for a couple dozen games produced a bit of insight:
1). My assists were sprinked across the spectrum whether I won or lost League Points 2). My kills were also typically in the 2~5 range regardless of victory or defeat 3). But my deaths correlated strongly with victory & defeat
The highlighted regions show where when our team won I had died about five or less times, but when our team lost I had died about five or more times.
