Shogun 2, also published by Sega, is a turn based game where an even higher percentage of players just play SP (where balance is not a concern compared to MP). But maybe this is a sign that a Relic RTS is about on par to a SP turn based game when it comes to business decisions based on the % of people who play MP.
'Tis a sad day, indeed. You'd think $100+ for a game would be enough, but
nope.
To be perfectly honest, I would have been fine with adding this type of paid game features
if the base game had been balanced thoroughly first and cleaned of all bugs and glitches. As someone said earlier, it is essentially what Opposing Fronts did but on a smaller scale.
However, with the way things are looking, if all these new mechanics are going to be released every couple of months without the prior balance and bugs figured out yet, then I'm afraid this game might never reach that vCoH level of balance everyone is waiting for.
There's enough problems in the game already that people are frustrated with, we don't need to add more (yay for German panzerschrek/LMG clown cars and T0 infantry spam).
You don't fix something that's broken by piling more potentially broken shit on top of it. You fix it by actually fixing it.
