Yes a battle prophet is viable class.
I just love mine. She can deal damage, somewhat tank and has can cast battle heal when it gets rough.
Soloing is difficult at lower levels since the prophet hasnt maxed out all the fighter buffs yet. Ive tried it a few times from 50-60, and I found it a quite viable option. Imo, a prophet can solo as well or better than most other DDs (assuming they dont have a buff pet around or bought a stockpile of l2day scrolls). Although soloing isnt the best xp option.
Now in groups/duos you have many options.
1) large groups: The traditional prophet with robes and mana up/conversion weapon. Not to fun to play, thats why most of these types of prophets are buffpets. Expensive if you still want a heavy set to do other stuff
2) Duo. BD would be best in my opinion. But with any other melee is good too. One of best ways to play a prophet. A duo with an archer is great... for the archer. Hes going to be uber and kill alot faster. However, this combination often ends being boring for the pp since the archer often kill sthe mob before the pp can get to it. Great xp, boring though ( excpet for running around and picking up drops)
3)Small group. This is the play style I enjoy the most. Good xp, fast killing, and not boring. In most groups the prophet would be sitting on their behinds and not contribute dirrectly to damage . An awfull waste of potential. A battle on the other hand can deal damage.
As I mentioned in a another post, if my party members can know if im using shots or not just by how fast we kill the mob (and without having to look at me) then she must be doing a substantial portion of damage in our small group. I deffinatly do more than half the damage a normal fully buffed DD would do.
But your battle prophet has to be setup properly !!!!
If you dont go all the way battle prophet setup , you will end up being dissapointed.
A darn good example or a good Battle prophet setup:
Sure, the Battle Prophet is a very interesting class. I have my main character a Battle Prophet, and Im in love with him.
Here's my details :
lvl 68
Weapon : Kesh*Dama +9 (350p.attack)
Armor : Tallum Heavy +3 all the parts (8% attack speed, +2STR)
Dyes : -5CON +5 STR
HP : 3950
MP : I dont remember :-P
With full buffs :
P.attack 930 (1026 with BD Dances)
Attack Speed 510 (585 with BD Dances)
Although personaly I love OE B duals with focus.
A battle prophet is an interesting class to play. Its a support/fighter hybrid. It was its up and downs as all classes. I love it. But to all people considering playing a battle prophet: dont expect to be a supper uber killing machine. Your a hybrid. That meeans that you dont get into the mindless grinding and repetivness of a fighter would have soloing, and your not bored out of your mind only buffing every 20 mins and some crowd control. A hybrid can buff, tank, deal damage, heal, crowd control....
