I plan on playing a Bosmer at launch but must confess, I feel like the Bosmers drew the short stick (along with Argonians) when it came time for the devs to dish out racial passives.
[Bosmers]
The first passive I think is rather underpowered is: Archery Expertise which boosts bow leveling speed by 15%. The thing that irks me about this is once you hit your level cap, this passive becomes worthless. There simply will be no more leveling to do. I would much prefer to see something like a 1% crit chance or 1% dmg boost with bows so as keep the passive useful even when characters hit the level cap. I'm aware that other races have 15% leveling speed increases but the Bosmer's is only useful when a bow is actually being used whereas orcs for example can milk their heavy armor 15% experience boost with just a single piece of heavy armor being worn. It just feels to me like unless you're dead set on being a bow wielding Bosmer, this passive has no use whatsoever.
Next is Resist Affliction: which increases both poison and disease resists by 8 and also increases max stamina by 1%. I don't really know of anyone who has gotten worked up over this one, to me is just screams "meh", unless you plan on grinding your way up through 50 soloing nothing but spiders, I get the impression that this passive will rarely be utilized. I personally feel that spending a skill point to get these resists isn't justified.
Probably the strongest passives for the Bosmer would either be Vigor or Stealthy. Vigor giving up to a 3% stamina regen while in combat whereas Stealthy improves stealth radius and increases dmg by 3% when attacking while stealthed. (especially useful while in PvP).
But the poor Bosmer just seems lackluster when compared to the mighty Khajiit who has both Carnage and Robust. In fact, the only reason one would choose a Bosmer over Khajiit is due to personal preference (e.g. roleplaying or aesthetic reasons) which saddens me, I would like each race to have some really unique and powerful passives that make it pretty difficult as to which to choose.
[Argonians]
Poor Argonians.
Let's start off with Amphibious: which increases swimming speed by 50% and boosts potions by 5%. Other than for making an occasional quick getaway in PvP, I really am puzzled to see why anyone would feel justified in pouring a precious skill point into here.
Argnonian Resistance: Again we see the lackluster 8% resist to disease and poison make another appearance. Once again, this passive feels rather "meh" for the reasons stated above with the Bosmers.
Quickmend: Increased healing by 2% This doesn't appear enticing either. It pales in comparison to the mighty Khajiit's 5% boost to health regeneration WHILE in combat.
Restoration Expertise: Increases restoration leveling by 15%. I could see dedicated healers who want to level up fast grab this but overall once you max out, this skill becomes useless and healing is generally seen as one of the more "boring" tasks within an MMO.
Would be curious to hear other people's thoughts on which races have the "best" passives and which have the "weakest" just to give the devs some feedback.
