There are some pets that could be a viable choice in PVP if they get some small tweaks. Giving pets condition damage was one of the bigger ones as a lot of pets had skills that did less power damage to compensate for applying conditions but no bite to said conditions. Taunt also isn’t as strong as it was before so it isn’t outright better than Zephyr’s Speed, so pets that benefit more from Quickness might be more appealing than pets with a low F2 cooldown.
Cats and spiders were already decent pets that saw some use. Now that their conditions do damage these pets basically got a straight damage boost and might be valuable enough to see more of. Cats have great DPS as is so they work well with Quickness, and spiders never benefited from taunt anyway and tended to be taken in non-Beastmaster builds.
Adding Healing Power would make moas and the sylvan hound more viable options, for example. The sylvan hound especially as right now it’s regeneration is weak and actually hinders those who gain it over regeneration applied by someone with healing power.
Drakes: Cut the cast time of their F2 in half and allow their breath attacks to track the target the way Rapid Fire works when the ranger isn’t moving. Drakes being able to land their F2 reliably would be a big damage spike that could see a lot of use in PVP. Their tankiness and base damage is already pretty solid. All they really need is the ability to connect with the F2.
Porcines: Have the F2 deliver the obtained item directly to the ranger’s hand. It still might not be super appealing because of the randomness factor, but you can get some strong effects from the forage skill which makes it pay off big. The main thing holding it back is that the enemy has an equal chance of picking up the foraged item, which is just dumb.
Devourers: Adding bleed to their auto attacks could help a lot. The tiny chance to apply poison isn’t really worth the low damage. Though now they are in direct competition with the Bristleback in the role of ranged condition application. Devourer could have a niche as a shorter range pet with more condition applications and more defensive options but with less power damage and less range than the Bristleback.
Bears: … I don’t even know. It looks like they were suppose to be the tank pet, but that doesn’t work well. I’d probably change the regen they apply to protection, give them cleave damage, and increase their power stat so they hit harder. That way at least the Brown Bear would make a good tanky, sustain damage pet with a condi cleanse attached to it’s F2 and maybe Black Bear could be useful for AoE Weakness application to hinder group bursts. I’d also want to add a taunt to it in some way. Maybe replace Defy Pain which is kind of useless when we can’t control when it’s used anyway. Just some way for it to grab aggro away from it’s master and tank the way it was designed. Put it on a lengthy cooldown so it doesn’t feel like you’re getting spammed with taunt.
