You should absolutely try to get siren, or awakened pirate. It'll skip steps when the lvl cap is raised, which is sure to have very high prices when the materials are in low supply at the start. The higher you can go before the patch hits, the better, as the prices are currently low compared to daily income, but once the patch hits, we're going back to high prices for like a month or two.
Alt leveling goes quick if you focus on it and don't waste too much time. Buy a 25AP diamond to put on the alt, buy a gem hammer so you can get the 4th socket for only 1 hammer once you have awakened blight, get at least 1 soup from the cash shop(hongmoon coins) or use one you got from daily dash that's sitting there, maybe 2 or 3 even, then at ~25 go to vulture dig and grind in there until 31-32 with soups on, will save you like 2-3hours in the desert. Try to find people doing Poharan 24 when you reach 43 and get the quest for a large boost of xp, or grind with soups at monkeystone or undeads in misty woods if there's no one, can do last 2 levels in an hour.
Total time is like 15hours without being too efficient, can go down to like 12hours. Can be done over the weekend pretty easily.
That said, it's no Dreamcutter, so not a huge deal.
