I don't know how much experience you have in the RTS genre, why/how you play this game, etc; so I won't make any assumptions and just start at the basics.
The average player wants to win. That's their goal. They are going to do whatever they can to improve their odds at winning. Let's say you're in Tib league, that means you have EIGHT DIFFERENT MAPS that can be randomly selected. There are simply too many variables to build a deck around. The only variable you can count on is that you won't have a deck optimized for the map you're playing.
So if you want to win you have to focus on that one variable. You will want to build a deck that's balanced and has strategic/tactical options on any of the maps. This actually leads to a very stale meta. Tech units are not a good pick at all for a balanced deck. So they get left out and players end up focusing on the units you get from the war factory. Yes, you can run into some players who don't play that way. But if you're of equal skill and have a balanced deck you are most likely going to win. Your chances of losing go up when they get lucky and the map favors their deck over yours.
Having an option to pick from one of three decks you've built after seeing a map increases the variety of units that you can competitively use. The way maps affect deck choices goes beyond "aggro vs tech". Even as GDI there are some maps in Tib league that favor MG squads over snipers, and others that favor snipers over MGs.
Let me break this out into a list:
I hope this makes it clearer, but it's really simple. Random maps lead to choosing between a stale meta or relying on luck.
Besides, what's more entertaining? Immediately having the upper hand because you got lucky or pitting your skill against an opponent on a level playing field?
Don’t b fool by some of the comments here. They are either EA staff or aligned to them in some way. This game is obviously not going to improve any better. Only thing would be to suck more money from you but do not deliver the best gaming experience. I hv made it my daily job to spread the news that this game is not worth your money. Take recently the resource challenge...cheats in majority of the matches. And the cheats is not from the players but from EA itself. What kind of cheats u may ask. Cheating u of your money by almost always matching you against players who always hv a deck that is superior to whatever deck you have. Outcome is to frustrate you enough hoping u will pay more to buy more decks. So all those commenters here who * about how to play and what strategy to win bla bla bla....my feedback is...if u can * pls allow me to feedback too. I hv played many EA games before....mostly C&C titles....this is by far the worse. If I am EA owner, this Rival team is the first I will sack for making many of your customers feel dissatisfied. My final advice...DO NOT SPEND ON THIS GAME. ITS NOT WORTH IT...ITS CHEATING YOU.
