So basically, the first nerf to ignore was that characters in hands cannot be ignored, so pre-block RTC would still allow your opponent to block with an EC of the chosen brigade from hand. Once the EC is in battle is where the more recent change comes in. Instead of the ignoring character winning the battle, it is a stalemate, as you mentioned. What did not change is that ignored characters still cannot enter battle, so pre-block RTC could still be good if you know your opponent has no ECs in hand. Probably not reliable enough to merit it's inclusion in a deck though unless you're running some sort of hand control alongside it.
