But that's the thing. Closed and mixed maps already allow you to utilize all 3 classes in your tactics. Random plains just throw in a different dynamic to the gameplay. And no...infantry is not the same as cavalry. The playstyle, approach, and thinking are different. If you play infantry one way, it doesn't mean it will work as cav, and vice versa.
Also, random plains being random, it doesn't necessarily mean all cav is always viable. If you roll a map with a lot of uneven terrain, you better field some archers and maybe even 1 melee. Good luck traversing that terrain with your all cav, while getting raped by enemy archers. Tactics that I'm talking about for plains is quickly knowing what terrains you're dealing with and deciding how many of each class to play, all within seconds at the start of the round. Then during the round, knowing how best to position your team if both teams are waiting for flag. Since you don't know where flag will spawn, you will have to decide how best to go to that flag if it pops up in an unfavorable position. On the other hand, in closed and mixed maps, you already know exactly where flag will spawn, especially with this new module that prevents flag from spawning in same area more than once. Therefore, you already know that if you setup at X and Y, you'll be able to cover flags A and B. So you go setup in those areas and wait for it to pop up. Very formulaic, predictable, and somewhat boring, especially if the map is old or overplayed, such as Sandiboush.
Of course, all these plains tactics don't mean squat if you have ****ty cav players, so that's where cav skills trump tactics. On the other hand, in mixed and closed maps, your team can be weaker in a certain class but you can still win if you have better tactics or are located in a more strategic location.
