Since the maps on the current event pretty much favor teams of comparable speeds, and I can totally imagine if people can't get all their squads up to 800+ speed, would you like to:
A. Play with a 444-speed trigger-squad (Cymbidium, Fritillaria, Apple, Cyrtanthus, Geranium) which kills most regular pest groups on the first round
B. Play with a 471-speed counter-squad (Hypericum, Anemone, Mirabilis, Rose, Dahlia) which is quite funny when a boss AOEs (sadly, no bosses on ?-4, I hope ?-8 has one)
C. Play with my regular 887-speed helper-squad
Yes, there is another squad, but few people find that squad even remotely useful (I personally do, but that's another matter) because it's made for increased solar gem drop rate. So I'll just leave that one out of the vote.
