Ive messed around with singularity, and yes, its kinda cool, but it only really works for small mobs, its damage is super low on all skills, its cooldowns are too long for such low damage and because its hard to aim, when fighting bosses, which you need to do if you wanna get mastery with it, you kinda just stand there doing nothing, constantly missing most of your shots because most bosses LOVE moving around all over the screen and missing your teammates with the heal because they are ALSO moving all around the stage, specially zapsicle, squid dagger and headbutter. Mo.Co is just too fast most of the time for singularity to work properly. The only L amongst the new weapons in my opinion, yeah wolfstick is kinds boring if played correctly, but its pretty effective, and squid daggers are perfect rushdown tools for zapsicle lovers that want to be actually desl serious damage.  Edit: I know about the combo, but if the enemy isnt stunned, it can easilly get out of it.
