ladder slasher is a relaxing long term game (at least for me) with several facets of gaming. you can either just collect guild points, try to reset the ladder, get a lot of profs, improve your gear as much as you can (your fg should will be a very good start), improve skills (fishing, cooking, transmuting, glyphing, suffing) and so on.
you can ofc send me a pm if you need more help since the most guides are very outdated.
