As far as Beta Viability go, Survival is the best tree.
While it doesn't quite have that many reliable, short cooldown tools like Marks and Silencing shot, it has at least A BIT of damage, it's focus is not awful and it has a bunch of significant % Modifiers, which always help with scalling (% bonus from Mastery, 10% extra damage with scorpid sting, etc). Mirrored Blades is ok, Wyvern is bleh, and that's basically where it differs from the other trees (Our combat style for all trees are too mirror'd, btw. Just saying)
Bestial Wrath is basically garbage for PvP. I know you said not to mention pets are squishy, but well, they are, and on top of that the damage is still "meh", BW immunity removal was the gutting of the one trick of this one trick pony. There isn't much left.
Marksman is dead until they majorly revamp talents, our Physical damage scalling, Artisan Quiver passive mastery (Wild Quiver is ok, Artisan isn't), among other issues. I'd honestly like to see Marksman as a much more physical oriented spec, in the same sense Rogues got Subtletly, and Subtletly got the tools to not be so hard-countered by armor. I know armor still mitigates lots of Sub damage but at least they have SOMETHING, yetthe Marks tree is still undecided - It does Chimera Damage for magic, Arcane shot for magic (Which now you spam al ot more than before for marks...) yet most talents seem to want to buff your physical damage, and so do the mastery.
Should just go with Marks as the physical spec and it would be k.
That's why Marks steady is so weak anyhow, because cobra ignores armor even for MM.
