Could someone let me know if Dwarves are beneficial end-game. I know they are needed for castles (I assume this), but is it like when a guild has one dwarf they don't need anymore??
Any person who *plays* a Dwarf will tell you the same thing.
DO NOT PLAY ONE AS YOUR MAIN.
Dwarves are 95% unnecessary, and those who watched the changes over the various chronicles are sure that the last 5% will be removed sometime in the future by the developers...it's just a matter of when.
Dwarves as a matter of design are the absolute gimpiest melee chars. Melee damage is almost wholly a matter of criticals in Lineage 2. He who crits the most and the hardest wins. And the main weapon of a Dwarf is a Blunt. Which it the absolute lowest critical rate weapon in the game by a significant factor. (Relying on a blunt user to do damage pretty much renders critical buffs ineffective...) And this is even before you realize that dwarves have the fewest skills both active and passive. The one 'main' skill they get is almost a complete waste of MP. (Stun) I say almost, because dwarves really don't get anything else to spend their MP on in combat...and if the dwarf is a BH, then the MP is far better spent on attempting to get a spoil than wasting it on a stun.
Dwarves also get polearm masteries, but having to find and AOE mobs all the time can be frustrating for many people. (WC buffs will be inadequate by themself for AOE in a duo before your pretty much in A grade.)
Bounty Hunters main 'skill' is spoil. Which is rendered weak and useless for all but a handful of spoils due to the extremely poor Spoil tables. Any other melee character using manor seeds has more material gathering power than a BH. Also a significant number of key materials are either aquirable via quest or simply don't exist as spoils at all. (B grade recipes and parts I'm looking at you!)
Warsmith's main skill is crafting/crushing. Except it only takes a tiny handful of 'crafters' in Giran to provide all the crafts a server needs. Plus a large number of players have power leveled some warsmith alts, and pull them out when they just need a thing or two crafted. (Or if you shout in Giran looking for one!) For crushing, it's often faster to just sell a whole item although there are plenty of alts who will trade you the items value in crystals for the item + a fee/percent.
This takes us to the Warmith's second set of 'skills', Golems. No matter which one your using, they are one and all expensive to run. The 'siege' useage Golems being obscenely expense, their cost can run in the Millions of adena *per minute*. And for the most part, they are unnecessary. The vast majority of clans would rather nuke, shoot and bash the castle doors down in about the same time for a fraction of the cost for a single golem.
Thus, many clans don't have much more than a warsmith or two for crafters (those often being alts or chars specifically for the purpose) and those without are hardly bothered by the lack. And when it comes to Bounty hunters, their only real 'sweet spot' as of this time is certain A grade armor spoils...and everything else is a waste of BH levels due to the Luxury shop, Mammon, Quests and the gimp spoil tables.
Remember: Friends don't let Friends play Dwarves as mains!
(Just play with them as alts like the rest of us. >_<)
