Spike grenades are fantastic and you ' ll see guys like Lupo and Gernader Jake use them to disgusting effect . They use them the same way you ' d use Lightning nades on a Titan . For zoning and territory control . They are great and I ' ve nothing against Spikes at all it ' s just for shotgunning I prefer voidwall for wombo combo . Spikes are great for zoning for snipers as they can cut off lanes and zone their targets into favourable positions or get them to retreat so they can push into a power position . My game is mobile . If I ' m outnumbered and in a 3 v 1 I ' d bait a team through a chokepoint and wombo the area I ' ve just come through to burn 2 people at once whereas with spikeenvenomed I ' d have to place the spike on a wall then the smoke on one of the targets which is harder to do under pressure . Both are great for different reasons and your playstyle will dictate what you like more . Rumble is about points per minute so stormcallersunbreaker are going to be superior to nightstalker in that playlist they have roaming supers and charged melees but if you ' re playing to improve and not to win which I ' d suggest at this stage then rumble will be great for your movement . shadestepping into cover , using your better control jump to bait doorwayscorners . Nightstalker has great mobility . Always be sliding in and out of cover and remember shadestep is a defensive manoeuvre not an aggressive one . Lumi will always shadestep backwards after a shotty kill to get in and out quickly but he won ' t shadestep forward into a target ' s line of sight . That ' s a common error I see from people just starting to play nightstalker . Another bad habit I had if you decide to run voidwall envenomed when I started with nightstalker was throwing the voidwall first as that was my grenade button then the envenomed . It ' s a mistake because you ' re using envenomed to trap the targets and the voidwall to burn them . Throw the envenomed first THEN voidwall . The only time you wouldn ' t do that is is if your enemy is low health and perpendicular to you and you know they are going to run round that corner in which case I ' ll throw the voidwall as it ' s horizontal line of void light will burn them .
