Weapon focuses
One noteworthy bit that sticks out for me is that we always see the same classes using the same weapons. Warriors always have a big two-handed sword and occasionally use what seems to be a buzzsaw shield. Spellslingers always have paired pistols. Stalkers always have claws. Espers always have... well, they don't have much for weapons, but they're certainly not rocking a gun along with those spectral weapons.
To be fair,
WildStar would hardly be the first game in existence to have each class use a distinctive weapon rather than having a range of different weapons. But we also know that it's possible to avoid stat stovepiping in large amounts, leading one to wonder whether weapons may even be more flexible than we know... or more cosmetic.
Consider the fact that none of the Espers we've seen seems to have an actual physical weapon, which is the sort of thing that would have come up by now. It's always possible that your weapon is fundamentally a bit of visual flair rather than a piece of equipment, opening the option for classes that have no hard weapon but use abilities instead. It seems unlikely, but it's been done before to great effect, and it would keep classes visually distinct without saddling anyone with useless items.
Or maybe these weapons just contribute to a more dynamic and iconic look at this time. It could go either way.
