How often do you see tactics anywhere? Just about any battle ends up with large amounts of vehicles shutting down everything outside of a base, then infantry zerging inwards. The change of pace comes with the change of scenery and layout. Southern Indar for instance has much more boxed-in bases where tanks are mostly cramped together, unable to go far off the roads. Amerish offers more elevation battles and mixes between Indar's boxed-in versions in the negative (Indar: fight in canyons where the rock walls are your borders with the occasional chasm or drop somewhere, Amerish: fight on small roads flanked by chasms and drops with the occasional rock wall or mountian as your border), and Esamirs open battlefields in the valleys that Amerish offers with more open combat, but still sheltered by lots of trees, foliage and small terrain changes and rocks dotted across the landscape. Esamir just offers much more freedom of movement for vehicles, battles are more spread out and there's a different amount of skill and patience necesary to flank enemies in the sparse amounts of cover it offers. It´s tough to say to no an argument that says `make it more interesting´, everyone wants it more interesting . But yeah, a bit more variation should be possible. The Ice caverns, frozen waves, Glaciers and evergreens are great idea's.
