So the target dummy often does not take into account the 30 to 50% hidden pet damage nerf for rated pvp for BM.
I play both BM and SURV currently and even with less gear (470 surv vs 476 BM ilvl) on my alts I do 15% more damage on average on my surv hunter.
I think both are viable in 2s atm, but BM tends to have longer games, take less damage, and do slightly less damage in return.
Also, your relative performance will be VERY different as BM vs SURV depending on comp. As BM I struggle vs DH / DK / monk teams but seem to counter 90% of lock / mage / rogue teams. As survival it’s the exact opposite, melee teams feel like a free win and casters are very hard.
Survival definitely has the better toolkit for 2s games right now, but I would expect tough games vs locks (which are almost a free win as BM).
I’d say play what you have more fun playing, and what you enjoy countering. The percentage of locks vs DH over 2k rating (for example) is within a percentage point of one another. The specs of BM and SURV both have comps they’re good into, and ones they will struggle against. You kind of have to pick your poison.
On the plus side for BM, it’s the strongest spec also for mythic + and raids for hunter atm, so you can be lazy like me and focus on a single spec to gear optimally for multiple situations (I have 3 different sets for bm pve and two sets for bm pvp). Trying to gear correctly for multiple specs and multiple situations makes my brain hurt.
For pvp as BM I recommend vers > haste > crit > mastery (due to the hidden pet/mastery nerfs in pvp).
For pvp surv haste > vers > crit = mastery (both are equally bad)
Feel free to add me if you want to talk hunter: Hog#1657
I’m a little higher as BM right now (2400 vs 2k) than survival, but I’m playing survival on my alt quite a bit, and I’ve been 2500+ as both since Legion.
