Precursor: Sorry if this has been spelled out before! To begin: There are 3 classes (obviously), Wizard, Warrior, and Priest. Wizard has 3 Trait "lines," that basically amount to "+fire damage," "+lightning damage AND block reduction," and "teleport at start of turn" Warrior has 3 Traits that basically amount to "+ bash damage," "+piercing damage," and "+chop damage" Priest has 4 traits that do the following "heal adjacent allies and remove negative effects," "Card Draw," "healing self and cantrip on heals," and "+ heal" What conclusions does this lead to? Warrior has the most narrowly focused traits. All require a subset of cards and collectively they don't cover all types of warrior damage cards. They also all deal entirely with boosting damage Wizard has the only traits with "tiers," as you can boost fire by +1 or +2, and the same with Lightning (although it's worth noting that the lightning boosts also add a bonus that decreases blocks on All Block against your Arcane Attacks). Similarly to the Warrior, the damage boosts only cover a subset of damage types, and the only non-damage boost comes from Dimensional Traveller. Even still it's tough to call that trait "generally useful." More generally useful are the lightning bonus cards, because they also boon all arcane attacks by making them tougher to block. Priest traits have the most variance. All of them do something distinct, and while it's clear that some are better than others, it's highly unlikely to be unable to find use for some of them for a priest build. To put it in another light, many builds simply use warrior/wizard traits for card cycling. The Specific trait doesn't matter, only that it doesn't take up space in the deck. On the other hand, priest traits in general have noticeable effects, and can improve or even change how a deck is played when they're attached. It's card cycling AND useful effects. tl;dr-Warrior and Wizard traits end up being similar, whereas Priests have a unique array of traits. Warrior's are stuck either building around the traits or ignoring them entirely, Wizards gravitate towards the lightning damage increasers, generally to make blocking any arcane attack, regardless of damage type (or damage at all) harder. Priests generally have choices but gravitate towards either increased card draw or card efficiency ( Altruism or Talented Healer) My opinion? Priests traits embody what traits SHOULD be. Not just deck change fodder, but interesting and helpful boosts that at worst provide a numerical boost and at best change deck construction and play. Warrior and Wizard traits merely at BEST provide a numerical boost.
