I think it just loads a random Online job.
The heists were the biggest disappointments. Rockstar did say crew members would level up before the original release. Little did we know it was pointless. You only use them in 3 or 4 heists. The heists themselves were great but the whole "planning" aspect was really underwhelming. You don't really "plan" anything. You make different choices to see different scripted events. I've said this before and I'll say it again, what this game needs is a heist side mission that you can perform whenever you want. Choose a crew, pick random locations in the city, prep, perform. It could work. But no, they'd rather have that be part of Online. It's a shame. It needs more action-based side missions. After 100% it has the same problem GTA IV did, there's not much to do. Hopefully DLC can remedy this.
I agree with this. I've been talking with my friends about this and we really expected something like the film "Heat". It's pretty underwhelming that Rockstar didn't develop that aspect as it easily is the most coveted activity.
Let's hope that they at least do a DLC.
