exactly my question as well. cuz i hear alot of this "archers are worthless" kinda talk.
i play an AA. i've learned some tricks.
first of all, an archer with no sense can screw things up, especially if he starts kiting so the melee cant do anything, but so can a melee' tank who is trying to bite off more than he can chew.
first thing i've learned is that timing your manyshots, and using them liberally, is key to having good dps. i'm not claiming that an archer can achieve the steady dps that other melee builds can (before you all freak out on me)
but you wont have good DPS as an archer unless you are using the PERFECT bow for the job. equipment is really vital. we archers don't have the luxury of a vorpal weapon.
i carry about 25+ bows and know my hotkeys intimately. an archer MUST examine a beast/boss more than a melee' fella who runs around w/vorpal 80% of time (if they aren't all greensteeled out) you have to examine that buggar and choose the right bow, fast.
but the number one tip for an archer is to let your fighters/barbs and mages get the agro first (usually while you examine the beast), then unload w/your manyshots, and the right bow, and make sure you're buffed for max damage.
i KNOW i've been a great contribution to the partys i ran w/while playing my AA. i've saved all of them before. i've assasinated bosses virtually single handedly, the fact that i DID grab agro, saved my party, and the fact that i was grabbing agro meant i was obviously doing more damage than anyone else. i also assasinate beholders before others even have to do anything. (acid/greater abberation bow w/force enhancements and conjured +5 arrows, manshot, goodbye beholder.)
my archer has darn good ac, and if need be, can turtle up w/a shield, sprintboost to grab soulstones and get the party back to a shrine.
having said that, an archer than runs in and starts shooting things far away, (just because he can) is dumb. just like a barbarian or monk who runs really fast ahead (just cuz he can) then brings a ****ed off mob back to a party taken off guard. especially when that monk or barb retreats back to the party on the verge of death, which i see quiet frequently.
my archer can give good buffs to the party (freedom of mvmnt, barkskin and heals, poison resist) and the fact that he isn't in the fray makes it easier for me to lend that kind of support.
but yea, a bad archer is a bad archer just like a bad fighter is a bad fighter. i will say that there are many instances where an archer will find himself in very close quarters, and it can get tough, i like to maximize my range, and if the enemy is suddenly agroed at me, i start charging it, leap over it's head (cuz rangers get jump too) and lead him back to the melee' fellas, this lets them get some flank hits in, gives 'em a chance to trip, sunder, or whatever.
i could go on forever. but i get invited to parties all the time which leads me to believe archers do have a place in DDO, it just takes more... style, learning to become really helpful. after all, we don't dump all our points in constituion and strength, and look for a vorpal weapon....
archers flat out own slayer areas, taking almost no damage while slaying in wilderness. bet me on it. bet me. :P
edit: oh yea, and i lvld my ranger to 18 so fast it's not even funny. ran abuncha quests solo, ran w/parties, yadda yadda
