Well.
Generally, its still 3 Main class from Rank2 and 1 Crit enhancement class.
Meta build would be something in between these two :
Ar2-Ran3-Sr3
Ar2-Qs3-Sr3
The alternative Rogue variants are :
Ar1-Ran3-Rog1-Sr3
Ar1-Qs3-Rog1-Sr3
I would really like to suggest completing either Ran3 or Qs3 before going back to take Crit enhancement class from Archer2. It’ll provide you an easier early quest running.
By the way, about off-meta SR builds.
Here are all of what I can think of :
[Ar2-Ran1-Wugu1-Fle1-Sr3]
-Various DoT spam. Wugu2 instead of Fle1 is okay too.
[Ar2-Ran1-Sap2-Sr3]
-Unmounted for trap setup, then remount back into combat.
Tricky playstyle though. But I’ve seen one person doing this.
[Ar2-Ran1-Sc1-Fle1-Sr3]
-Kinda like… PvP oriented? Scout is there just for emergency escape and waiting for Retreat Shot cooldown.
Make sure you turn off your companion as fast as possible when you use Cloaking.
[Ar1-Ran3-Fle1-Sr3]
-Sacrifice Crit enhancement circle for Broadhead Arrow in PvP.
But this build will suffer a lot in PvE instead since you have no Crit enhancement.
