With PKing out of the picture, you don't have exactly have an overwhelming variety of builds to look forward to. The first ones that come to mind are:
A) A wicked skiller.
B) A maxed main.
C) A maxed/hybrid/tribrid staker.
D) A PvM range tank.
It also kind of depends on whether you're keeping the account or planning to sell it. For instance, I would go for a quicker build like options A or D if you plan on selling the account. Ultimately it's all preference, though.
If this is your first account on the game a main would the best option, get 83/83/83 via Nightmare Zone and then max out the rest of the Melee stats via Slayer.
