I've grown to like Zavod. I think I can easily like any map as long as it meets two criteria.
1) Infantry and vehicle use is balanced throughout, making both viable, generally leaning towards using the former more frequently. Vehicle wank maps are bad.
and 2) Map design and flag positions lead to a natural flow of entanglements and tactics across the map with a nice ebb and flow of ticket balance. That is to say there's lots of great battles going on all across the map, and not just one big fucking meat grinder in the middle as back flags are ignored.
Last few matches of Zavod, despite the map size, have suited both those criteria. Vehicles are strong, but infantry is highly valuable, and a tight play of tactics/squads has everybody fighting over every capture point, not just fucking around in the middle two.
