Hitech would never remove it from rotation for such simple terms. As I recall, Trinity was ruining any hope of real rotation of maps. The size and difficulty in player resets almost insured a near 50% chance that when you logged on, it would be the map in play. Since then new maps have been added along with some older ones reworked to also be included. There were a number of good things about trinity, that simply wore old, due to its overwhelming dominance in rotation time.
My hat is off to all of those who create these maps and to Hitech for allowing such important contributions from players and volunteers. Who knows there may be someone reworking Trinity or rotation rules to help bring it back to those who would like to see it again. That being said, it was a smart move by Hitech to allow the current rotation take place as well as their continued dedication to improve game graphics and game play. So, as ImAdot has pointed out one could always find their favorite map in Custom Arenas.
Another thing to take into account, woud be player preferences. Some of my happiest moments from Aces High I can recall was on an old map the spawned the Dueling Arena Lake concept. The action was purely sport, no base capture intended but tons of players, just as happy to go down in flames as long as they were able to quickly return to the fight and return the favor to another combatant. Long flights to reach the action and a quick death, certainly does not favor many players with lesser skills. One must ponder how long a paying customer would subject themselves to that sort of abuse, without some sort of encouragement. Even if that means base capture, or more player map resets.
Thats because the large portion want to horde a map and win it in 5 minutes or less, and they find out they cant do it on trinity unless two countries attack one, because even with an NOE raid on a field, the other country can react slow and still recover and defend unlike other maps.
Trinity has had some of the best fights that I can remember, doughnut map for example I can't recall many good fights unless it was a horde.
