Actually, all 3 countries have pretty great battle locals amongst each other, that flair up to 30 vs 30 tank fights quite often; V83 in the South West, and A1 to the East are a couple that pop to mind.
NATEBO
*sigh* They're pretty entertaining battles, no doubt, but never more blatantly against the spirit of the MA (or a qualifying map). The DA - instant tank battles and all - is thataway ladies and gentlemen. If I want gamey unrealistic shoe-box spawn on spawn tank battles, there's a half-dozen other games better for it (with a design and settup centered around that form of gameplay). Further proof of it disqualifying itself from the MAs and the MA-style of gameplay... three countries and two spawns... both each ontop of opposing spawns, one in a canyon with one side have an unbalanced advantage, the other between two mountain slopes at dead-ranges. I think it's only fun if you're lucky enough, otherwise you're stuck on a horrible and unfun map that shouldn't be (and thankfuly isn't anymore) in the rotation.
Why?
I thought it was definetley not good; not enough CVs, bugy and gamey vehicle spawns, 10k canyons and 20k mountains to encourage plenty of spontaneous action across the fronts, a neglected ignored and overlooked tank town and assets in the center middle, overlapping towns on bases, absence of shore batteries for costal defense of bases, wide spread of air bases...
Why? You makes no sence.
The (large) map is roughly 33% water, yet each side only gets 4 CVs, 2 for each front and with starting postitions (at closest) 8-setors away. The few and far sea battles are maybe only awesome because the 10k canyons and 20k mountains on the starting front lines are so conducive to plenty of spontaneous action on the fronts or lack tehre of? I assure you, it is not from it's generous supply of CVs for sea battles and engagements, although I agree with you that when they do finaly arrive the action is best to be had on the map.
Land battels are a joke on trinity. The towns overlap many bases, necesitating deacking and often flattening all hangars before base capture is possible. Many bases do not have dynamic vehicle spawns available, in that after defending they can go offencive. Of the few dynamic spawns, and especialy along the front lines, there are gamey and unrealistic spawns that for the most part shouldnt be in the MAs (they also only exist on two of the three fronts, and they are unbalanced - both valid reasons to not be in the MA.). If instant tank action is wanted, there are bases for it inthe DA. If gamey spawns so tank duels across a canyone and fron two mountains is desired - go make a custom terrain and host a private arena. The MAs are for MA gameplay.
Air battles... until you break through teh fronts along the 20k mountain ranges and 10k canyons, are few and far between compared to many other maps available in the rotation. The few choices at the onset funnels most air combat into specific and confined areas... a waste for such a large map, really limiting player's choices, and mostly causing a concentration that many (especialy this weekend!) voice much disdain over in the MAs. If you don't like feeling constrained and limited in what options you can make - don't look to Trinity.
