Group dungeons, showcase group reunited, death knights set free

Characters now run dungeons as a group with real roles, the showcase group gathers and levels together, and the ten death knights, stuck for over a day, finally play their starting chain.

Group dungeons

Tank: leads to the next boss, pulls one pack at a time from range then backs up to the healer, waits for the group, lets patrols pass, asks for polymorph or sap on big packs.
Damage: 2 s head start for the tank, boss adds first, melee from behind.
Healer: tank first, heal sized to the missing health, resurrection after a wipe.
Loot: "Need" only for one's armor type; upgrades equipped.
Test bench: Ragefire Chasm cleared with zero deaths (showcase group and a Dungeon Finder group), Scarlet Monastery finished by the showcase group, Deadmines completed (1 to 3 wipes left).

Showcase group reunited

The leader (the tank) picks a zone suited to the least advanced member; the others join by zeppelin, ship or orb, then follow, share quests, and the healer heals the whole group. Test bench: 0 deaths per hour as a group vs 2 to 5 solo. In production a first fix was needed: group logic and transports were reserved for characters without a client, while the showcase group always plays with clients attached. Four of five members now quest together in the Ghostlands.

Death knights

The ten death knights were waiting in Acherus without a weapon. They now play the starting chain: weapon retrieved and engraved at the runeforge, initiates, Eye of Acherus, quests from Mograine, Thalanor and Valanar, descent to Havenshire. The two steps impossible through plain client packets are documented scripted steps.

Other fixes

Battleground: a stalemate against a self-healing opponent is abandoned after 3 min.
Wands: casters buy one they can afford.
Character loading: timeout raised from 5 to 20 s.
