I replied according to the numbers you set in place but as a side note this topic seems to be more appropriate for the #Feedback (This can be transferred by replacing the hash tag in the edit thread option. 1#: Nova Bomb is as it states a bomb and with a name like that you can naturally expect there to be collateral damage if your inside the blast radius. It isn't intended to be used as an answer to a close range engagement but rather a crowd control weapon to take out a mob at medium to long range (depending on your skill tree set up). Other supers don't kill you or damage you because more often than not you are the super in physical form rather than casting it out. Simply put you can kill yourself with Radiance if you through a grenade and walk into it but this rarely happens because players use them effectively. 2#: The animation speed with all supers is different and has nothing to do with how powerful it is, it is mainly cosmetic and also gives opponents (PVP) to react to the incoming threat if they can. Nightstalkers shadow shot may be faster firing but it cannot kill groups with a single shot (on impact) and has 3-4 stage depending on how it is used before it becomes effective. 1: Activation, 2: Firing/Travelling, 3: Impact/Kill, 4: Tether activation. Some classes have invincibility frames on activation such as Fist of Havoc and Nova Bombs. There are perks or armour pieces that will make your significantly harder to kill with them stacked with the already increased super armour you gain from them. If your being killed mid Nova Bomb it is because you were either low health before activation or your opponent had a good weapon and used it effectively or they used a counter super. 3#: I myself have a played very little of voidwalker since the dark below, i transferred from xbox one to PS4 a couple months ago but in my experience with hurling the nova bomb with or without lance you will get pushed in a direction depending on where you were moving when you fired the bomb. Movement speed also play a part in this as well. 4#: As for ads and orbs of light different enemies create different amounts of orbs (not including major or ultra ranks). So you will create more orbs of light if you bomb 5 fallen vandals as oppose to bombing 5 dregs. I'm not sure on the specifics but i think it's safe to say that there is some form of orb per class kill calculator and when you kill a group it tallys up the enemies killed and drops orbs of light accordingly. This is just my opinion but i've been a destiny player from the Beta and have hours of experience on both Xbox One and PS4, so take it as you may but in my opinion i think the voidwalker class is quite stable at the moment and i see no big problems with it.
