I would be curious as to how this is determined @kalishane, when you are looking at the actual “participation” of solo events vs. faction events. Are you looking at the individual RAW scores of those in the faction events? Because often times, in FACTION events, people are working as a TEAM to meet the Objectives, and are less focused on Individual scores. So if they Data they are looking at is the Player Scores in those events, of course they will be lower, because in Faction Events people are playing smarter. That does not mean they are less engaged. But when you can achieve an objective with 3*, 4*, and in some cases, even 2* characters, most players will do this in a Faction Event. Of course to overall picture will look as if players might be less engaged because individual scores are lower, but they are working as a Team for a Team Score. Solo Events are a whole different beast. Higher benchmarks for milestones means we have to pull out all the stops to hit them, so no way can relying on those 3* for objectives be the mainstay of scoring. 5* and 6* and Scavenger Missions are a MUST, and thus the scores are exponentially higher, giving the illusion of greater engagement. This has to be taken into consideration when interpreting the raw data.
tl;dr Solo Scores > Faction Scores =/= Greater Player Engagement; It’s an Illusion and False Interpretation of Data
