How to level dps alts?

[t0rn]

Dungeons with fates while you wait, maybe get the yokai's done if you haven't yet. 70-80 fates have the perk of gaining gemstones and rep with the areas for goodies and riding maps for the zones. If you hate fates then maybe just tab and do something, slap on netflix or whatever your heart desires.

Is doing low level fates via Level Sync efficient?

if you have to sync to a fate its probably not efficient leveling wise at all. I do them more as time passers for the dungeons which are the real meat of exp that isnt POTD. On aether i've found que times arent too too terrible, 10-15 mins per que unless its super late at night, then the time stretches a bit.

you can also run some dungeons with squadron, though it takes practice and time to get the squad mates up to par. I am talking independent, offensive, or defensive order level. Level 4 or 5 is what you want. Once you get there you can burn through mobs pretty quick.
as for fates it depends. ARR not so much unless you are waiting for queue or something. Lvl 60-80 (StB and ShB fates are ok xp, not the best but not the worst).
Roulette all of them even frontline. Cool thing you can swap from a dps you a leveling to one you are familiar with in PvP. If anything you get some wolf marks and ok xp.
PF for a specific dungeons for leveling as I see that from time to time still.

Make sure to eat food, fc xp buff, wear xp buff equip as well.

In general, you want to be doing the highest level content you have available to you. So, after roulettes you move on to your highest level dungeon, and you do FATEs at or close to your level whenever possible while waiting on queues. This does mean you have to actually upgrade your gear as you level, but you can do it.
