Just as a quick, data snapshot - I thought we could post which content in game we are purposefully "Abandoning" and which bits we are "Playing" and "Why" as to help Cryptic with their future design decisions. To make things easier, break it up by campaign if possible and by default I'm excluding the leveling zones (1-60) and by extension the Third Eye campaign since they contain less grind and are generally only revisited when one goes through the other campaigns/doing other things.
I'll start off, so feel free to copy my format to make it easier for yourself.
2x Character Level: 70.
Time to Play: 1 to 1.5 hour per weekday, and say 4 for weekends.
Notes: Obviously I'm very time poor, so when I say things "take too long" below, it's that they take too long for my schedule only
Finished campaign. I only run the weekly for ADs if I need them.
Finished campaign. I only run the weekly for ADs if I need them. Abandoned gauntlet making too since they've never pulled something worth more than it took to create. The lairs are too long to run so I skip those as well. I make an exception for Phantasmal Fortress every now and then though simply because I love the design, and the boss.
Finished campaign then abandoned this one entirely. Reward vs Effort in that area is simply not worth it. Abandoned Black Ice crafting too, especially since my powered armor no longer needed empowerment. Mining black ice to advance the profession is not fun for me, it's more like work. I work enough with my day job thanks.
I only PvPed for the armor set to survive Icewind Dale. Pretty sure I killed almost no one during that time. :P Not really a pvper so I've now abandoned that.
Tyranny of Dragons/Tiamat:
I only run the weeklies (Portal Defense and Elminster's One) for ADs if I need them, and spend lots of gold purchasing Coffers from other players to do so because the Coffer drop rate is lousy. Tiamat too long (and really, quite repetitive). Lairs take too long. I'll probably never get the last two boons since Linus are few and far between. 80 linus for two characters? Yeah, that's not happening.
I try to do the daily influence grind (first 3 only on each char), and should the guild need it, I run dailies in whatever overland area (only the overland quests) that requires that currency (Sharandar, DR, IWD, WoD) - the only motivator for me to do so. Dragonflight is fun, but I'm not too interested in it since it rewards me with boxes I cannot open (free-to-play-er here). As such, I've no interest in Dragonflight armor at all. Not interested in PvP either but from the tutorial I could see that even if I was, the majority of the time would be spent traversing the huge map which is useless vs people on purple mounts and better.
Finished campaign. If I have spare time, I slay Baphomet for the ADs. Bruenor's dailies are too long due to the travel distance to compete with quicker, more rewarding tasks.
Finished campaign and abandoned. No interest in revisiting any of the areas, not even for the grind of those new elemental weapons. Skipped most lair quests towards the end because they weren't necessary, and as usual, take too long. Go into the Slaad Temple and fight your way through to the boss or do a 30 second jumping puzzle. Lol, is that even a choice? Note this was during EE's first iteration of vigilance tasks, I've not played it after all the changes since then.
Storm King's Thunder:
On-going with the campaign. Intentionally skip the "Give a man a fish" quest because it is time consuming, poorly designed, annoying and honestly, illogical. Not going for the new armor which needs empowerment because firstly that's too grindy, and secondly my previous nice suit of empowered black ice armor was made redundant. No point in going through all the work if it's just going to be nerfed any time in the future. By extension this means I won't have the Everfrost requirement to ever run the zones for the elite but I'm okay with that so long as the story doesn't get gated behind it.
Abandoned all. Unless I really need to squeeze extra AD out of regular ToS, which by default is never thanks to the new AD bonus thing. Despite not liking it when it was introduced, I must concede that it does actually work to my favor.
Throne and Madness are the only ones I might be tempted to run since they occasionally give benefit to the stronghold and are time limited which means either way they end in x minutes. Unless required though I generally skip them because again, they simply take too long.
