I log on, check the gobbie box, type /l Anything going on tonight?, wait 20 minutes with no response, then log out.
If there are people on the LS, maybe take some initiative and suggest a specific activity instead of just waiting on other people to decide what to do. Skirmish? High tier fights? Get an etched memory farm or CP party going? The guy who just hops on to the LS to say "anything going on tonight" usually got ignored even in the busiest times of the game, not surprising that's still true in 2015.
Personally, I've been doing:
LS activities: Vagary a couple nights a week with the LS. Occasionally oddball stuff like Incursion, DM, getting some people who missed the VW era clears so we can go see Prov. Watcher for fun.
Solo/small group times: been doing UNM, high tier fights, and CP farming. I've really gotten into solo high tiers, though losing the double exp campaign this month slows me down a little bit from spamming 4+ fights then refilling 45 merits. Still want to do the last update's Adoulin quests concluding those lore questlines and getting the rewards, will prob hit those this week.
Long term quest: After finishing up Kenkonken earlier this year, instead of grinding another mythic I decided to get 100% reforge+1 AF/Relic/Empy for my 10 maintained jobs (will prob expand that to the mule WHM+BLM too). Currently 50/50 119 relic, something like 38/50 AF, and a lot lower Empy. Been having a really good time working toward that long term goal. Chapters are my big roadblock, I already have all the upgrade materials I need. So I've been doing any high tier fights I can get, and still have some 109 empys to finish up because of empy NM trophy drops I never bothered to get.
Haven't even gotten to: Escha. Barely touched it, though I'd like to start doing it soon. I imagine the LS will transition into it fairly soon, getting started in earnest with phase 2 from the next Rhapsodies update.
Job wise:
My NIN and RUN, and to a lesser extent PUP, have taken up the majority of my attention. Haven't even had time to get back to BLU and farm my new spells since the last update, but I'll do that too.
Apparently RUN is a trend on this thread, and I'm on board. RUN is quite good for a lot of stuff now, particularly (1) high tier avatar fights and (2) a lot of Unity NMs - both things that I've spent a lot of time on in June and July. Arguably better than a good PLD for avatars, since single element magic damage is so perfectly tailored to RUN's strengths. Personally, I don't often use it in most LS alliance content like Vagary or Incursion though, since we have a good mythic PLD as main tank and I tend to DD.
I've played RUN since day 1 and it did kinda suck on most stuff (notable exceptions of WKR and Marjami/Kamihr Delve)... prior to the enmity system changes and the AMAZING Empyrean reforge set (I say RUN got the best set of any job). Now it's a very viable tank, if you have decent gear (and no, you don't need mythic weapon for that - if by that the comment meant Epeolatry). Yeah, you can toss on a DD set and a Macbain or something and do decent damage (great for your CP farming, low tier "bring whatever" events, etc.) - but the job was never designed to be a top DD, so you shouldn't be surprised to be getting destroyed on a parse by a SAM, BLU, NIN, DNC, etc. I'm aware that people who just play the job like it's a gimpy DD do sometimes make it look bad, but that's more an issue of not using the job for what it's good at.
