T.L.D.R.
- UDLs can give you starting gear.
- If other easy UTs are available (read: jungle staff which would work even at 4/8) then run those dungeons if you can
3.If you just want to follow the absolute rules and max yourself, find a rogue to rush 25 sewers. I cannot see why not though.
4.Depending on class you either do sprite worlds intensely first or hit the labs for def. Class dependent because a unmaxed melee/wizard can collect the mad lab loot easier, get the expo faster. When you have maxed dex run labs. - Run everything else.
A healing class makes things easier, but potentially slower because the DPS tradeoff.
