Crashtroller: out of the vicious circle, with a pet and a filling purse

Crashtroller was stuck in a vicious circle: broken weapons, no coins picked up, deaths one after another. The causes are fixed. He tamed a boar, reached level 12 and has not died since.

What was wrong

His bow and axe had been broken since the night: a broken weapon deals no damage, so he could no longer kill anything.
While the player watches the game, their client instantly closed the loot window opened by the server: Crashtroller picked up neither money nor items.
Taming the scorpid kept failing: the client finished the last movement right as the channel started, which interrupted it.
The training dummies in Orgrimmar (levels 60 to 80) made the city look deadly, so he never went to see his hunter trainer.

Fixes

Hunter: the bow is repaired first when money is short.
Disarmed and broke: he hunts very weak prey to earn enough for repairs.
Loot opened by the server is no longer closed by the client.
Channels (taming rod, Tame Beast): fully still and facing the target before casting, nothing else during the spell.
He actively looks for a beast to tame nearby.
No second taming when his pet is dead: he first goes to learn how to revive it.
Resurrection: no more back and forth between the corpse and the safe spot he picked.
Vendors: he also buys cheap armour pieces when his gear lags behind.
Flight points discovered up to 400 m away, roads followed more closely on long trips.
One server crash fixed (a destroyed item was read again after abandoning a quest).

Result

Boar tamed, revived and fed, level 12 reached.
No deaths in over an hour of play, against about ten per hour this morning.
He sells his loot and repairs again.
