You reduce the nova warp duration that is way too short, useless and un-fun at all.
You need to increase its duration to make it last longer. You need to make NW to go a longer distance with a little more cost. No kills of going thru walls. Walls block nw. A lethal damage blow.
Let's hear from people about NW. Maybe they can improve NW.
