To be completely objective here, I do think it is worth the time to restore extremely rare, high-level pets, only if they are lost due to a server crash.
For people who might think we're crazy, here is why Broken Tooth is a Naxx-quality epic, and why losing him is a huge deal:
1) Pets do not scale with hunter stats in vanilla. The only way to upgrade your pet is to research the best one, tame it, and level it up.
2) Broken Tooth is irrefutably the best pet in pvp, and under most conditions the best pet in pve. There are multiple threads about this. BT is a pet that will last you from MC through Naxx, nothing replaces him up until BC. He is a Naxx-grade pet.
3) Broken Tooth is the most difficult pet to tame. He spawns every 7.5 hours and usually around 10 hunters are waiting for him, often times more, and some show up just to kill him.
4) BT starts at level 37 and takes weeks to level to 60, months if you do it casually. It really does take forever.
5) If you are a BM hunter, BT saves you 1-2 talent points. You don't need 5 points in Frenzy if your pet's attack speed is 1.0, compared to 1.5 of the lvl 60 Winterspring cats.
Based on the time it takes to tame and level BT, which is on par with Thunderfury, and since BT is irrefutably the best pet in pvp and pve all the way up until BC, and since BT can basically give you free talent points as BM, I have to conclude that BT is at least on par with a Naxx-quality epic. GMs restore BWL epics, which is actually really nice of them, but BWL epics will be replaced. AQ epics will be replaced. Broken Tooth will not. It is the best pet until BC.
toolshed has kindly gotten involved in this topic, and as he said he is afraid that his BT could disappear without any notice. I suspect that many other hunters feel the same. They shouldn't be afraid to use their BiS pet that they worked hard on to tame and level up. Also, if they want to invest time in taming/leveling a really good pet, they shouldn't have to weigh the risk of it randomly disappearing. They should be able to play their class. Here is another post of a hunter losing his pet during the same server crash as I did, though I assume it wasn't a rare one:
https://forum.nostalrius.org/viewtopic.php?f=45&t=32963The GM team concludes that restoring one pet means adopting a policy to restore all lost pets. I don't think that logically follows. There maybe 1-2 pets total which are worth restoring for hunters, and they may only be worth restoring if the pet has been significantly leveled up.
An example: as much as I hate racism in the game, which I write about a lot, I do not think that investing GM resources into sanctioning racists is more important than restoring a BiS pet. I can just /ignore racists, they don't impact my dps as a hunter nor cause me to waste weeks of my time on a pet that disappears from a server crash.
