Okay so I'm new, and having some trouble figuring out what exactly I need to aim for on my WSE in terms of lines.
I'm on challenger world as an attempt to fresh start and figure things out away from a handful of 200-250 characters on bera where I used to play on occasional basis, then hopefully be ready to hop back in once it's over.
This seems like a good secondary, to me. Obviously I'd probably want like, 2 or 3 boss lines, but for just the free cubes I get, this seems okay enough, right?
I'm not playing a class with any built in IED that I know of (kinesis), so the extra IED is pretty nice, and the line brought my boss% up to around 300%.
my emblem is 9% matt 9% damage, and a trash third (I know damage isn't great either but I don't have any spare cubes to throw at it and don't want to put money on it before dmt at the very earliest so it stays for now)

so, would I be better off keeping the IED/boss line if it keeps me around 94% ied and 300% boss, or chuck it to try and get matt lines?
