Guild Wars Shop Skills in pve?

I dunno whether the skills at the guild wars shop can be used in PvE or not. Can they?

No.

padding for short limit

The shop skills unlock the skills for PvP. Even though they are unlocked, you still must own Prophecies in order to use the Prophecies only skills you unlocked. You will unlock some core skills in the Prophecies unlock pack, and those will be usable if you do not own Prophecies, but it's not worth it still if you do not buy Prophecies

In PvE:

Once you have unlocked a skill in PvP, it becomes buyable from all PvE skill trainers who's respective chapter includes that skill. For example, if I unlock Tiger's Fury, I can buy it in PvE from all skill trainers in Tyria, but cannot buy it from a Canthan skill trainer because it's a Prophecies only skill.

Does it unlock the elite skills for PvP?

They implied this wouldn't be the case for skills unlocked via the uas pack. Has someone verified that skills unlocked via the unlock pack are available at skill trainers for pve characters?

Yes it does
