How important do you think "flashiness" is to hero design? Which heroes do you think are the most flashy?
As a tank player, D.mon is the first new ground tank I've been interested in years and she also seems to dwarf heroes like Ram, Mauga, and Domina when it comes to how exciting her gameplay is (especially after recent changes to her fluidity and mobility).
When I say flashy I mean exciting gameplay. Good carry potential, exciting clips, fun to watch played at a high level, has some fun strats/techs, etc
How high of a priority should flashiness be when designing heroes?
Which heroes do it well and which don't?
Can it be unhealthy?
Are there any heroes who could be more exciting with some changes?
