I usually play on my alt hunter as BM, but want to try survival again, haven't played for quite some time (couple exp pack at least).
And my buddy, also hunter, told me what explosive shot, if you spam it fast enough, do not lose additional damage as dot so you can go ahead and use it as soon as it off from cd and during LnL procs.
I was always pretty sure what you have to wait until dot from explosive shot to run off, before applying additional one, to make a full benefit of it.
Looking for info on this matter.
