My Ranger Build for PVE
first about fb, the problem is that buff are capped to 5 people and if the all players are in the range they will be preferred for the buffs, what is okay in my eye´s and a good mechanic and with this buff, the buff that you get will be shared to your pet.
this is why i never play longbow in, there are a few exceptions, but most time nope it sucks
so than your build, you rly should take the forst spirit and nm IV, its the best buff that a ranger have for pve groups and if you rly want the max dps you need to play sword, if you not rly good in melee combat cuase of expirence you should start with gs.
For dungeon, I would take Sword/Warhorn for power based build or Axe/Warhorn for condi based build.
Warhorn because you can pump out 6 might to your party if you and your pet can blast the flame trap that you can swap with viper’s nest and a drake that has the tail swipe.
Also, Warhorn’s blast comes the moment you activate it, which allows you to make multiple blasts if you get interrupted while it’s casting.
Frost spirit would also be good for 10% damage buff to the party
Sooo
Stuff I suggest changing:
Warhorn, Drake pet, Flame Trap, Spike Trap, Frost Spirit (which you can change to Soth when running)
