Can't rush like in classic. But, i can however, help you with gold, arcane crystals, waypoints and median xl gems(resists) and killing faster than you in zones near your level for faster exp.
You can technically still be rushed by having a higher level player kill monsters for you in areas that are around your level. You'll need to grind a few levels on your own early, but once you hit nightmare at around level 60 you can gain massive exp in Act 2 Sewers/Ancient Tunnels (Lost City) and around level ~80 for Act 5 red portals. Once you're done with a few A5 red portal/cavern runs, you'll hit level 100-105 pretty fast.
