Sentinel sp1 used to be fun to evade, not too easy so felt rewarding to punish it, until they broke it in 22.0 update month ago and not fixed till this day (even though they lie in patch notes that they did)
Venom's SP2 is my favorite to evade. Must be because when he was AQ map boss early on in my MCoC career he'd eat my lunch on a regular basis, so I had to learn to evade to survive.
