This is sort of a "hey, cool!" post, nothing really asked in here.
I've found, if the conditions are right, I can actually get pounce-FFF-mangle-shred-shred in at the start of a fight. This involves OoC proccing, as well as being talented for it (2/2 brutal impact and 2/2 shredding attacks) in addition to mashing the keys fast enough (and probably a little bonus from lag) but when you can get that massive openning chain in...it really helps a fight out.
