I would love to see a bit more detail in the statistics after the match / in your career summary to help with gear and helix choices.
I´ll give you an example as to why I think this would be good:
During Beta, while playing a lot of Rath f.e. I was wondering how my damage came together. Rath in his helix tree has the choice to improve lifesteel for skills, autohits or both (to a smaller degree ofc) … but without some data on what exactly dealt how much damage during a match there´s no real way to calculate the most efficient choice.
Now I know there are ppl who dislike min/maxing and having everything be about numbers but then I gotta say the helix choices are poorly composed in that case … all choices basically improve the very same thing, but there´s a “best” one.
I´m sure there´s similar cases on other characters where a more detailed information on how your damage/heal or whatever is composed would help with the helix or gear choices.
I think there are cases where post game stats (in the achievement tab?) display how much damage a specific skill dealt but that´s not there for every character and basically a pretty pointless information if it does not cover other damage sources and whatnot.
