Your most hated post-turn in scripted sequence?

[Maxion]

Get JAMBA the mboxing addon.
you open the quest giver on all 5 toon and then select complete quest, and all 5 do it.
there is an option to have it complete the quest on all alts with the same reward selection ( works best if they are all 5 the same type like 5x DK )

otherwise have all 5 select their reward option and use the script described by others.

But not for the ones this tread is about, some npc's simply wont accept more than one turnin at a time, even with jamba or a script.

That one quest in eversong forest (or what ever it is called, the belf place before ghostlands) where you turn in this book to a guy, and he has to throw it away and cast a fireball at it, before anyone can interact with the npc again, every time.

Yeah, there are a few that seem to have a little pause between the click and the start of the sequence, allowing multiple toons to turn in before the NPC goes wandering off. There are a few others that will only run the sequence once every couple minutes or so, so you only need to watch it once. Almost all of them, in my experience, only allow one turn-in at a time. I have a macro for almost everything and it hardly ever works to get in all five turn-ins before the script starts.

That druid in Hellfire when you show her a rock that's next to those mine-able giants.. She walks down. Plants it and you fight a mob. It does that close the window and does dialog thing. It seems hit and miss but so far Ive had to do it at least 3 times for each group ive gotten that far.

There's that quest in dragonblight, down on the little island to the south. You click on an item, and summon a big sea monster. The sea monster takes a half a minute to arrive then goes into a speech. Then you have to make sure your alts are not on follow and jump off the cliff. Make sure your toon is not under the water, otherwise jump until her head is above the water line and she won't drown. Wait for speech to end. Wait for item to be re-clickable. Click on next toon. Wait a half minute for the sea monster to re-appear. Listen to speech. Jump into the water, make sure not to drown. Wait for speech to end. Only 3 more to go. blah blah blah blah blah.

I am a software boxer (aside from the fact that i have two monitors) and The Tears of the Moons quest worked for me using /script CompleteQuest() and /script GetQuestReward(1).

It did not however work for all 4 of my toons when using the Jamba AddOn, so yay for scripts!

[Gomotron]

I hated the Scarlet Monastery quest line in Wetlands, I believe, where that dwarf upstairs in the inn takes the quest hand-in and does something for what feels like 5 minutes each turn-in.

One of the more annoying leveling-up quests I have done has been in Ashenvale. There's a Chalice (Chalice of Elune?) that is a ground spawn in Satyrnaar that takes 20 minutes to respawn. And of course typically gets ganked by rude people just as you are trying to click it.

As the opposite of this I must admit it was fun to launch 5x Hourglass of Eternity on top of each other, items which supposedly can't be set down within 40 yards of another one

[Mooni]

NO, there is NO way to fix this!
In fact, the best you can hope for is one of you completes it and you don't go thinking the rest of you completed it and hearth to Silithus (remember Silithus?) or something.
You know you love that - seeing the quest still show up on QuestHelper for 2 days because you never actually completed it on characters b, c, d, and e.

[Stormweasel]

It isn't actually the turn-in part of the quest but the last quest in the Keristraza chain in Coldarra where you have to line up and take turns shooting the flare gun to get picked, fly around, then land as she gets taken by Malygos. Having to use the quest item perfectly or triggering a long cooldown plus having the quest fail because the npc dumped you on the ground and told you to run (even though you have to be really close to her to get credit). I only did that on two characters and I wanted to hurt someone.

This. On 5 it made a little part of me die inside

[Hachoo]

The Keristrasza one I think I completed on all chars at once because I left them sitting at the "end" point.

My worst one I can remember off the top of my head is in feralas - turning in the muisiks or whatever and he takes them, goes and does a dance by the water trough, waits a minute or so, then comes back, waits another 15 seconds, then lets another person turn the quest in.
