Quests that shouldn't be taken immediately?

[Sarcasmo]

When playing KB: The Legend, I remember there being some quests that penalized you for taking them too early. For example, the werewolf quest in Greenwort could be failed if you weren't powerful enough to complete it right away, and there was a quest to kill a barbarian that prevented you from getting a decent shield if you did it too early. Are there any quests like this in Crossworlds (Orcs on the March campaign), and if so, is there a list of them anywhere?

In TL you forgot Ultrax , getting dragon eggs. If you go there and just take eggs and run away without fighting 3 dragon battles, there is no way to return there later when you`re strong enough to fight so that`s around 3x4000 exp lost.

As for Crossworlds there is :
1) on Uzala , orc islands talk to all npc in tents/shops before talking to heroes standing around (hunter quest gives you more exp if you kill hero, then brontor army).
In cave, before attacking enemy hero, talk to him and take quest to kill frog on Dersu island
2) on Shetera, demon island dont attack any enemy hero before talking to every npc there. There are 2 quests that give you reward for killing enemy heroes, so if you kill them before taking quest you`ll lose around 10K exp.
3) ... i`m not sure if there is any more.
