Dual-brand cadence
When two IPs share a window, events often alternate chase goals: one champion skews PVE sustain, the other spikes burst or control. Read the event text before you split resources evenly.
Visual and tone shift
Crossovers temporarily reshape UI skins, trailers, and dungeon dressing. It does not change core mechanics, but it can distract from calendar discipline—keep an eye on energy and shard math.
Long-term value
Licensed kits sometimes age into niche picks for faction stages or secret rooms. If you only care about meta Arena, skip; if you love collection depth, plan books slowly.
