So I only really played D3 for the first 3 weeks of release, until I realized it wasn't viable to play Inferno with my (at that time) lousy computer.
So with a new computer I'm looking to try it out again, but as I only got D3 through my WoW sub, I never had any interest in getting RoS. So how would playing "vanilla" D3 work out for me, did it get all the updates that came with RoS (personalized loot and all that?). What am I missing out on by not buying RoS?
For comparison, would it be very similar to how vanilla D2 and LoD worked out, with the extra act/extra classes that a vanilla player wouldn't be able to do?
