Hundred blades and evade
Always been like this, as have all other channeled attacks.
If you need to evade, you can break the channel by moving, then evade as normal.
How were you managing to evade before without moving? I’ve noticed some channels seem harder to break than others, reviving an ally and 100b among them. In any case, as Tamasan says, this is neither new nor a bug.
