Which talent trees at escort quests are worth taking?

[Chattius]

I play mainly cornac characters just for the extra talent point. So sometimes i am really considering taking a talent tree at an escort quest. The main problem is that taking a tree takes one talent point to have the tree at 0.7. And you need 3 general/class points to reach 2.1. But if you are lucky and get for example 2 sun paladin escort you are at 2.0 too - and no talent point or 3 general points wasted.
I had great fun playing a cornac shield berzerker, taking shields and pushing shields with another talent point to 1.1 to reach stun and knockback immunity.
My first character in b19 was a cornac arcane blade who stumpled into an alchemist escort at level 4. So i thought not much time wasted and i selected the staff tree, not for shooting, but for melee combat. I put 5 points into staff mastery and i like to be able to change damage types by just changing to a different staff. I do the quests in order and i stopped yesterday at level 14 in the maze. Wonder how far i will go with this weird character...

So what is your experience with these talent trees you can get at escorts, anyone ever took them? Which class/escort_talent combination could work?

As it turns out, you are incorrect. At least some of the escort quests give the same .7 mastery on the single talent points.
