1.IOD, Sharn (My favorites): Good quest design; IoD have a good saga xp and Sharn have excellent sagas xp; Quests can be completed quickly, even solo; Quests with good XP/min and fair; The missions are straightforward and the puzzles are simple; You don't waste your XP Potion time; The Items are good for leveling; Wild (Only IoD): it is fun, the quests aren't that far apart from each other, teleports in good and strategic locations, you don't waste as much time on your XP potion; and IoD and Sharn are good for R10 runs. Both are excellent to repeat throughout your TR's life; IoD can have some good endgame items for casters and Sharn endgame items are outdated/bad. You don't need to complete the raid to change or upgrade your items, it is really good

3. Feywild: Good XP/min and fair; Good quest design; Most of quest can be completed quickly solo; Quests straightforward; Bad saga XP; You can waste some of your XP potion running to the quests, no teleport to quests (or close to them); Slayers is not that good for epic levels; Raids are really fun to tank and heal; Excellent items for leveling; Good for R10 runs; Good to repeat throughout your TR's life; Endgame items are outdated/bad

- Relenteless (Raid) : This raid have really bad mechanic. The Grab/Stun is really annoying if you are healer or tank, because the time is too short for someone save you and Break Enchantment have a short distance to cast and save allies. Melee DPS have to stop to damage boss sometimes, while ranged/casters can full time DPS. The Mist mechanic was cool, but they removed it, you could cast Obscurate Mist (for example) near boss, when the boss spin it did not hit melee/tank. Good point: some items are good and the time to ress is very low (almost zero)
7. Shadowfell, Menance: have good xp for epic levels; good saga xp; items are not good.
8.Saltmarsh: Skippable pack ;Bad XP/min; Bad quest design, mosters are too strong for level 3~5; Some items can be good for leveling; No raid; Bad slayer; Bad endgame items; Bad Heroic saga xp; Good Legendary Saga Reward; Not good for R10 run, but some quests is really good to learn how to do R10 solo.
8. Vecna: Skippable pack; Good XP/min and fair; Some quest have bad design; 1 quest is really boring (Bark and Blade), it is like a walk-simulator, not that straighforward; Leveling items are not worth; Some legendary items can be good; Can be exhausting to go through the whole saga both heroic and/or R10 runs
- Fire over Morgrave(Raid): This raid have good mechanics; It is fun to tank and heal; Raid items are bad; It is a quick raid, good for Fates
10. Myth Drannor(My Worst Pack): Most of quests have a good XP/min and fair; Most of quest have a good design; Most of quests are straightforward; You going to waste your Potion XP duration running to quests; The quests are very far apart, and the teleport doesn't help; Most quests can be completed quickly solo; It's really exhausting to go through the whole saga both heroic and/or R10 runs; Excellent Heroic XP saga and Legendary Reward; Rare system is really bad; Good items for leveling and endgame items; After that pack, I started wondering if it's worth buying the new expansions or waiting. Worst mechanic is that you need to complete the raid to upgrade or change the items, it is really bad and annoying, specially for me, because I like to test different builds and classes.
- This pack have 2 Long quests and 2 Very Long quests: 3 of them have really bad design (The Zulkir's Plan, Times Long Past, The Key to the Mythal), they are really boring, the XP are unfair, they were not designed to be repeatable. The Key to the Mythal is the worst quest of this game, for me.
- Threats Old and New (Raid): Tanking this raid is a real boring. It is very punishing for first-timers or characters with few past lives. There is only one Shrine, so casters need to manage their spell points carefully. The raid is punishing for casters and healers because there are oozes that drain spell points. If someone decides not to follow the plan, the raid can become very frustrating and it can take a long time to complete. The items are excellent.
This list is based on my experience and what I enjoy doing in the game. I like to test different builds and classes, so I need all Heroic, Epic and Legendary content.
