We are talking of server side features that cost A LOT to be not only implemented but to stay in the game each month.
What? Why would it cost more to have a 1v1 with 2 spectators than it would to have a 2v2? I don't understand it at all. The real cost for spectator mode is coding it into the game, adding buttons and menus and stuff to the UI to support it, implementing a system so that spectators can join specific games, and so on. These are one time costs but since game development is so rushed and frenzied, any time you have your coders and artists make spectator mode, that's time spent doing that which they can't spend on something else.
Relic wants to have their coders and artist spend time on XP unlocks for their microtransactions, on implementing a bunch of fancy ribbons and medals to win to unlock new intelligence bulletins, and on customizable commander trees so that they can sell bonus commanders with the preorder deluxe edition. These are things they do to appeal to the masses, who love earning +10 XP and ticking towards the higher rank, but they're things that people who play competitively and care about the game competitively don't care about (or even actively dislike because they have to unlock all this crap or just buy it before they have all their options ready to go).
So like I said, Relic is catering to the masses rather than to the minority that cares about things like spectating. If Relic really wanted to save on server features but also cared about competitive players, they would just cut 4v4 and 3v3 because those modes are basically a joke, but of course Relic would never cut those because casual players love the no-pressure, 2 hour artillery spamfests that those games turn into.
All this "boo hoo Relic loves us and I just KNOW that they want to put in spectator SO BAD but they can't because if the game fails then they all go bankrupt and will have to be homeless in Canada" stuff is beside the point. OF COURSE Relic wants to add everything we want into CoH2. Do you really think that you'd ever talk to Quinn and he'd be like "uh no fuck you guys, we don't care about half the shit you want." No way! He wants CoH 2 to be the best game in the entire world, and every time you ask him "do you want to add X" of course he'll say "if we had time/money."
But game development is all about making choices, and Relic has made lots of choices to appeal to the masses in terms of gameplay features and as far as I can tell they've made zero choices to improve CoH 2 competitively compared to CoH aside from mirror matches (which half of this forum seems to hate anyways). I'm not saying that's the right decision or the wrong decision in terms of making money, but I suspect it's the wrong decision in terms of making the game better, because I think casual players are going to enjoy CoH 2 about as much as they enjoy CoH whether or not it has all these stupid little unlock things that unbalance the game, but I know FOR SURE that competitive players and the community that springs up around them are going to like CoH 2 less because it has no spectator mode, and competitive players and the tournaments and shoutcasts and streams that they lead to make the game more fun for EVERYONE. They turn it into a spectator sport, they make it easy to advertise to people who have never heard of it or who think the trailers don't make it look exciting (and by the way, the trailers DON'T make it look exciting unless you're already a hardcore fan), and they keep CoH 2 alive for a lot longer.
I know that the reason I bought CoH was because Tales of Heroes made it look so exciting. Before that, it was just another one of the crapload of WW2 RTS games that come out every year. Live tournaments are even more exciting, but without spectator mode we won't be able to run them.
And as for people like LeMazarin saying "well at least we'll get it after launch," well, I wish I could share your optimism. It's not impossible, and maybe it's on the list of things to add, but I wouldn't hold your breath. Relic has done some crazy post-launch stuff before (they entirely rebalanced DoW II) but I just can't imagine some producer at THQ sitting down after CoH 2 had launched and saying to themselves "I think I should give Relic a big bundle of cash to pay a programmer and an artist enough to implement spectator features." Hell, THQ is probably going to just abandon every aspect of CoH 2 that can't be turned into a new microtransaction, because THQ needs the money baaaaad.
