Guild Wars 2

Currently combo fields in zergy environments just become noise. You can’t really teamwork in combos in that environment unless it’s really basic (spam water fields for healing, etc). Either through items/runes/settings you should be able to tune your character to a specific field. These fields become highlighted through all the visual noise and you can combo into them even if they aren’t the last placed combo field (you’d still be able to combo under regular rules however when your attuned fields aren’t present).

The first placed is the one that counts.
