Last Saturday Onnmacmahal posted the large overview of the planned changes to the Hunter and Burglar traitlines “currently” planned for update 45. Over the last few days there have already been some updates in the details, but the changes to the playstyle of each specific traitline is still the same as the original posts linked below

Blue line (medium changes)
For the Huntsman, the following changes aim to keep the gameplay distinct from Bowmaster. With no inductions and greater access to bleeds and Melee Damage, the Huntsman playstyle would retain its focus on mobility and flexibility with the ability to deal potent burst damage through a combination of bleed cashouts and rapid-fire Focus spender skills.

Red line (specialty changes)
For the Bowmaster, the following changes aim to maintain the status quo of the resolute long-range archer, releasing a continuous stream of high damage arrows as long as you’re able to manage your Focus and use inductions relatively uninterrupted. You may notice that several passive sources of Induction reduction have been removed from the outline below. Passive induction reduction has crept up so high over the years that many Bowmaster Hunters have grown accustomed to having at least -75-85% Induction durations at all times. In this outline, we’ve pulled back on that a bit in exchange for higher direction damage, slowing down the flow of skill us a little bit in favor of more potent individual arrows.

Yellow line (major overhaul)
For the Trapper of Foes, the following changes aim to overhaul this specialization into one capable of matching other true support specializations (yellow-line Lore-master, Burglar, and Mariner). These changes would minimize this specialization’s focus on traps and roots, which are both awkward to use in combat and functionally less useful than the abilities available to other classes. In their place, the yellow-line Hunter would have greater access to more useful CC like stuns, mezzes, and knockdowns delivered with more ranged skills and more interaction with your Focus resource.

Blue line (playstyle changes
For the Gambler, the following changes aim to update your skill flow to be a little less reliant on stealth and feel a little more distinct from The Quiet Knife, with a focus on gamble effects and bleeds. Gambles would be a little more dynamic so they are not just maintenance buffs and would interact with more of your skills than they currently do. Importantly, blue and green gambles would be buffs applied to the Burglar rather than debuffs applied to your target.

Red line (minor changes)
For the Quiet Knife, the following changes aim to remove your reliance on positional to deal adequate damage, and make it a little easier to get your critical skill chain started through skill combos while removing gambles and making your core gameplay more distinct from the Gambler’s.

Yellow line (major playstyle changes)
For the Mischief-maker, the following changes aim to update your overall kit to better match the effects and potency of yellow-line Lore-masters and the other support specializations. These changes would also clean up some awkward and frustrating skill interactions (such as those with skills that currently apply Minor and Major Rent armour).
Tricks and Trick Removal skills in particular are statistically potent but not very fun or interesting to use in practice (half of your tricks are not useful in the vast majority of scenarios, and trick removals treat tricks as a very limited commodity despite the fact that tricks have minimal cooldowns).
Additionally, Burglar debuff potency would be drawn back in line with other classes by removing Trickster’s ability to double-apply tricks, as well as by tricks becoming mutually exclusive even between multiple Burglars.
