Star Gaurdian Dodging Practice
So, probably most everyone who played the Star Guardian event remembers the literal dodgeball that was played the majority of the time from the Velkoz.
Honestly, while that game mode was fun, that is the most memorable part to me... because there was a practical purpose to it that transitioned into regular games.... the ability to dodge.
In a custom game mode, it would be fun to set some difficulties of something similar to the Velkoz where you have to dodge and weave and make it to the other side.... a way to add PvE into the PvP game and still have it practical and useful for normal games as well.
