This is a question that needs to be asked, as it is potentially gamebreaking. If a player has unlimited stamina, they can perma block the entire battle whilst burning you down because you will never be able to get thru their block. It would also make vigor a potentially OP heal due to the fact one could spam it without end due to this bug. There are many issues that this bug could cause. If you all thought stamblades were OP before; well, you guys have not seen ANYTHING yet:D
ZOS, if this bug is a real thing, please fix it ASAP. not in 3 months, NOW. I beg of you.
