Aside from answering to the poll, please, write what makes a shadowpriest a fun class for you or what made it a fun class in TBC (that is, if you find it lacking in WotLK).
For me it was:
1. Unique abilities, that were so good, that everyone wanted me in their group and that there was no serious 25-man raid without a spriest.
2. An interesting spell "rotation" (or rather: list of priorities), as opposed to every other caster DPS. Yes, I love SW and having no set rotation.
3. The coolness factor of Shadowform and of playing an evil priest.
That was the main points. Point one will be no longer a case in WotLK and point two will partially diminish as well (for example: SW will no longer boost your dmg as much, as it did earlier, so I'll probably won't use it every cooldown anymore). And I see nothing compensating for the said loses.
