Kms Future Plans Q/A

Anyone out there that's got the numbers, I'd like a little calculation:

No crits.

Buc's using S.trans whenever possible and spamming demo, then uh.... using barrage during the cooldown... just barrage for the four minutes.

I want to compare that ^ to demo if S.Trans had a cooldown so you're only out of transform for 1min. How much stronger would this be? Would this allow them to outdo TBs on a lightning weak boss? How much faster would demo have to be? (All of this can either be exact or rough.

Please
