Unlock expert roulette if you haven't already. Research facility is usually good for a law bonus once you've run your roulette for the day. Use those to get 170 gear and a piece of 200 gear.

Hunts are dead ATM, but you can do your daily/weekly hunts to purchase upgrade materials for law gear.

Once you hit 170 you can run Alex normal for 190 gear. I'd reccomend getting belt->accessory->glove->glove if your focus is just ilvl. You'll get a free accessory once you clear a4.

Once you get bored of the dungeon grind for ESO, which will happen, you can play seal rock for a quick 20 ESO apiece.

Hope that helps.
