#ms-chat can answer a lot of questions, but depending on the ongoing conversation you might be a little ignored.
Any specific goal you have? Do you want to just reach a higher level or do harder bosses as well?
Some good daily things to do are monster park, ursus and daily bosses (specifically gollux and arkarium). Daily quests for symbols are also good.

Some things are harder to give advice on because I don't know your level or gear progression, but for legion you can start working on the basic link skills. Not sure which you already have, but some nice ones are:
Mercedes, exp
Evan, rune duration
Aran, combo orb exp, not that great at later levels.
Hoyoung, some ied but mainly extra dmg on 1st hit
Demon slayer, boss dmg
Demon avenger, damage
Kanna, damage
Luminous, ied
Lynn, boss dmg
Explorer mages, ied
Phantom, crit rate (if you aren't 100% yet).
Explorer thieves, dmg
