Any Soulsborne "titan" boss. It's not only lame to attack ankles for an entire fight, these things tend to have a tiny little weak point head that, when locked onto, will jerk and swing around enough to give you motion sickness. If you don't lock on, well, good luck doing 600 damage per hit to this 20k health pool that, despite being an ancient drake of frozen bedrock, can hop and float around the arena like a cat. Oh and it's attacks are all hard knock downs except for the instant laser it shoots when it tracks that you pressed the "heal button".
