Quote from TaylorCompletely agree with you there. And if people aren't interested in the single player they won't have any incentive to buy them outside of custom games...Though, I’ve got a friend who is a major Starcraft 2 nut and it sounds like they’re doing some pretty conservative changes to it. The Black Hole ship seemed to be a good example: it used to be a one-only, end-game uber-unit that could destroy a screen irregardless to what was on it, but it's been reduced and reduced until it’s pretty much a normal unit. They seem very scared of messing up the balancing and new units could be a spanner in the works. I’m not saying it won’t happen, but I think we’ll have to wait and see.
Yes I agree its a good example to conservative things happening but I think you are drawing the wrong conclusions from it. I don't believe they made it into a "regular" unit because they were afraid of messing up the balance, I think they made it into a regular unit because it was actually messing it up. Blizzard has always tried to make sure that things are well balanced and when you are going to make a sequel to a game that is so successfully balanced then I understand completely that they will mostly just copy what is done in the first game. When you look at it that way, trying new things would actually be time consuming and worthless since you can't really make something perfect better.
