You say that as if all Nightstalkers regret that they can't have Snare and Courage of the Pack at the same time as Envenomed and Lockdown. Besides, Fusion and, more so, Solar Grenades are better than people give them credit for when compared to Firebolts. With the reduction of the timer for Radiance when using Fireborn, Radiant Will could actually make a difference now and Gift of the Sun is a perk that Titans often resent because they need an Exotic to achieve the same effect.
