It depends what your focus in fighting you have on fighting maps. If you just make some stupid horse moves and dances that´s cool and can help you to kill some ranged units, but it´s not the main thing there. If you play as I plan mostly to play (and how me and TDL played mostly in the 1st Battletournament) is, to use all possiblities that you have also in a building missions. Splitting up melee and ranged units is a key there imo. If I see most playes in tactic maps just attacking in the same groups AND formation, as they are from the beginning, I don´t want to hear their opinion really. IN economy games you also don´t have normaly 50 bowmen in one group, but rather 2-3 groups with 15-25 bowmen.
Mostly it´s in economy and tactic that way: "You do most damage with the smallest groups that are possible to control." That´s the way cmowla win many missions in Singleplayer. The only Problem on this sentence is the part with "that are possible to control".
So there are many possibilites in fighting and eco maps, but many people just don´t think of "micro" in these things.
If anyone says "Fighting on fighting maps is too random" or anything else, like you quoted Blud for example, Sado. Well KaM has a random fighting system. However that works in eco and fight

For me such quotes are sometimes also a try to find an excuse: Now if I for example win with TDL nearly all games in the First tournament of battle and won all battles so far in the 2. Tournament, noone can tell me
You had just more luck than all other 25 players had and you had more luck in all 50 games, you have won.
I agree that it´s random. Sometimes you have more swordmen than the enemy has axefighters and you loose a battle. This random-aspect can be minimized a bit with ranged units.
That´s also the only part in KaM that does so, because ranged units can "flee" from a fight and they can move when someone is attacking them. (That´s why I don´t like KaM maps without ranged units in total

)
Back to the fighting system.Many of us should know how the fighting system in the Remake and in KaM works:
If 2 swordfighters attack in the same direction and you come with another swordfighter(group) from an 45° angle, the enemy get´s a bit more damage!
If 2 swordfighters attack in the same direction and you come with another swordfigher(groupt) from an 90° angle, the enemy get´s even more damage from that!
If 2 swordfighters attack in the same direction and you come with another swordfigher(groupt) from an 180° angle, the enemy get´s the highest possible damage!
For most of you that´s nothing new. HOWEVER I don´t see these tricks in most strategy AND eco maps. If you have one meleegroup fighting with another meleegroup and you send your knights to kill these melee units FROM BEHIND, it will kill them all in a few seconds. What some people do, they send like 10 knights on 40, that doesn´t make sense at all.
The things that I agree are, that many fighting maps have strange armyconstalations (20 bowmen, 20 lances, 20 knights, 20 swordmen/ in building you would have 30 bowmen, 10 lances, 30 swordfighters and 5 kngiths e.g.)
However if you win this way (both players have the same amoun of army), I can tell you that you also improve your fighting in ECO maps when you have more than your enemy
I though know many players in eco games that have a great army but did terribly after PT and I know some people that have nearly no army and still do a very good job at PT. A mix of both is probably the best,
without an army it´s not fun, without fightingskills also
I also agree that without an army, you can´t win an eco game. However I do really bad sometimes in eco games, if I don´t play for a longer time. Some of you may noticed that I can still beat a guy some times if I have like 3/4 or even less army than him, that actualy depends on the fighting skills of the enemy. If that depends that I´m also quite decent on fighting maps? I guess so Ladies
About Ben´s quote, true but his quote shows directly his opinion. He is the "Simcity" guy and that´s it

Like you mentioned with your example of Conquest (I would say Battle of Octumn is even a better exmample) it´s not that you have to fight on one place only. Some maps /special maps have nearly the same fighting situations like big eco maps.
My posts just shows my personal opinion. It shouldn´t also show like "YEAH I´M SO GOOD IN FIGHTING GAMES", it´s just an example that it can´t be that random... Also I don´t want to say that other people opinions or quotes are false, I just say why for me they are wrong/incorrect 
Sorry also for some mistakes in my post, it´s late already
