Hi there,
I think it would be cool if we had feedback on the total damage of some combo bursts we do. All we would need is a damage meter that piles up the numbers, and it could reset when no damage was done for 1 second.
For example, having a 4,356 Lightning Surge and 3,212 Arcane Wave hit at the same time would display “Damage Burst: 7568”. The Number would really slowly fade away until you do more damage, where it would add up if the damage is done during the next second, or reset after 1 second.
In large WvW fights and PvP it would be really interesting. If you want it to be an eSport than that would certainly make it clearer to see the total burst damage people do.
