You'd be surprised how fast ants can be. My pet Camponotus grow into 6-legged racing cars when temperatures rise above 30°C. They can easily rival spiders and even perform small jumps, similar to those that Huntsman spider do.
Actually now that I think about it, temperature influence would be a really cool thing - if it's colder most arthropods and amphibians/reptiles move and act at much lower speed (even deadly fungus would develop slower and aphids gave less honey dew). Even the brood development time could be affected.
Some animals - and even individual ant species - would be more affected than others which could make fights easier or harder depending on which species you fight and which ants you breed.
Even hotter and colder spots could be implemented with hotter spots allowing for faster brood development and faster honey dew production in aphids which both are essential to outcompete and overrun the enemy. That would actually allow for strategic positions on a map.
