Hey!
WHat is the recommended bow spd for pvp? im not sure what bow to get yet, should i get the slowest or the fastest? or both? thanks!

check your info of your bow and watch the effective dps.
(dps= damage per second)

in general you should use the weapon with the highest "effective dps". (weapon quality,condition,level - all play into this)

slower weapons deal more damage with one hit , faster weapons deal less - but overall they do the same damage over the same ammount of time.
on bows both can be good.it´s a bit more complex than this but i guess this is what you wanted to know.

at close distance (where you can get only 1 shot off) a slow bow would deal the most damage. at medium distance a faster bow could get a shot more off and thus deal more damage.
you´ll get a feeling for it pretty fast.

best technique i´ve figured out for pve would be this:
critshot at max range with a slow bow
followed up by a normal shot
turn around
sprint away from the mob
stealth
repeat

can level like this without downtime. takes some practice , maybe you can get another shot off between the 2nd shot and running. depends on your bowspeed and the distance to your target.
