I absolutely agree that there should be a DLC pack by now. The game is 2 years old. Unfortunately, Bioware hasn't even released a cheaper DLC pack for ME2. I seriously doubt they will care enough to release a pack or even discount the DLC for ME3. They discount prices for the PS3 and Xbox versions all the time, but the PC version continues to go unnoticed. They're missing out on money, so it's bad business, really. You would think someone on their marketing team would have mentioned this by now.
There's a lot of people that aren't buying this DLC because it's just too overpriced. It's absolutely ridiculous to charge more for a few items of DLC than it is to charge for the entire game trilogy. I personally haven't bought an ounce of DLC because I will not support its pricing.
It isn't right to keep the price the same as it has been all these years for both ME2 and ME3. Time to change, Bioware!
