here is how i view warforged, just personal believe. please feel free to correct any mistake i may made through this post.
Pro:
25% stacking fort by nature- these can only be find in end game(10%) and epic (25%)
underwater breathe- you can breathe in water starting from level 1, even at max level it means you save one inventory spot for something else
+2 con- the most important stats of all. for any and all~~ no one can live without hp~~ at level 20 it means 20 more health, plus the racial toughness enhancement provide much much more hp compare with most race
Immune to Poison, Sleep Effects, Paralysis, Disease, Nausea, Fatigue & Exhaustion- again you have save load of inventory and equipment slot, as you need not worry any of these.. plus some of these don't even have gear to provide immunity..
auto stablize- an free diehard feat...
lord of blade deity- the only melee two hand weapon diety with ton of great great sword in game..like epic sword of shadow..
specific class design for this race: Artificer(get advance version of construct essence without a feat slot)
dominate several class: archmage wizzard, sorc, Mechanic
dedicate role: tank, especially at lower level they are the only race that can reach 100% fort. at end game they are the best tank race due to the fact that both arcane and divine can heal them, and both very well if they know how to build their toon.
good in all area: unlike other race which are only good at certain area, wf are good at all area and class..
con:
recieve 50% effect from positive healing- big deal, there are equipment, shipbuff, enhancement to boost your positive healing, boost it to 100% isn't hard at all~~ plus you also gain healing effect from repair spell. this is one of the key feature which make wf the best tank race in game. there are no gear nor ehancement that increase repair healing effect, which make their 100% repair healing very vauleable.
Rust monsters and ooze- meaningless.. at least i can't recall any ooze/rust monster boss at end game..other then the red name rust monster in evon 5.. but then again it won't be any of problem since it isn't powerful at all..
-2 wis- a dump stats even to most fvs and cleric.. tank monk might value it, but then again..1 ac is not that big of deal...not when you have over 100 ac at end game..
-2 cha- again not much of problem, even for sorc.. the ability to self healing is just so much valuable then 1 spell dc..
-increase damage from fire/acid- seem to be a lie.. i test it on lam and find nothing alike. nor does anywhere meantion anything about this.
-no dragonmark- dragonmark are useless now...even halfling's mark can be replace by silverflame/heal potion/scroll/wand/hireling/player
personal suggestion:
improve construct essence feat
improve dragon mark feat
