First @ topic: I dont think it´s not all about the playability (does this word extist?) of a bow-barb... just think about the style... i will create a bow-barb after my crossbow-assa, hurrican-arma-fury-wolf, polearm-necro (gnahahaaa walking death ^_^ ) and the second version of my melee-amazon, just for seeing this kinda fat (Yes the barb is fat!) guy with his little bow shooting onto monsters next to a bu-sorc and psi-assassin and i will win... the style-contest! It is right that you can not use the other barb-spells very effective but in 7.60 there are many possibilities to strengthen those new playable chars, e.g. the new "sting" onto you 2.slot for enchant, dead-hc-doll for poison or cadaver-explosion at 2.slot with this unique polearm (dunno its name) or just put a huuuuge weapon at the 2.slot and run amok. Nvm you won´t be as good as a mainstream-character but you will be good at all and that is what it is all about... a playable fun-character
The new barb-mastery in fact is the weakest of the new skills. Paladin will be very good with his Mastery, the sorc will become tri-elemental very easily with a good archon-staff with enchant + cl + fo, the melee-amazon will be have great damage!! on both physical and lightning (i calculated ~0,2mill. max light-dmg if all cb´s will hit + a huge load of phy-dmg with the new spear-runeword which has +3ama/425%ed, +20%light/-20%light, 10%DL, 20%DS and tons of other stuff), druide is like paladin and with the ability to cast hurrican and cyclone armor while shape-form he will be very very good and the necro-mastery will be very very very useful in the early game because now you can finaly LEECH with a dagger cuz of the mass-damage and AR (and cs ^_^ ) and the fact that you can cast psn-dagger onto a polearm made my prayers become true! Just find the polearm-mastery-doll + psn-dagger and you will be the walking death! I can not await to start off with this brand-new-character ^_^
Last but not least, the cross-bow-mastery of the assassin! The best of the new masteries ^_^ !!!
Look at this crossbow:
Doubleshot Machine
Pellet Bow
Required Level: 55
1 - 3 to Multiple Shot
100% to pierce (missiles only)
150% - 250% Enhanced Damage
Socked (2 - 3)
40 - 80 to Minimum & Maximum Damage
And think about the mastery + venom and you still have enough skill-points to max out shadow-master and all the light traps. You will do Phy/Psn/Light/Fire-Damage and very much of all of them and think about Multi-Shot and a shot-frequency of 11fps (2.2 attacks per minute) with BoS level10 and 24% ias... that´s less than nothing! So you also have enough item-room for using +skills, resi and defense-things. (Dont forget CoS so you can hit everything)
Phew, that´s it.
Have a nice day ^_^
