Hot potato atm in shadowpriest.com is dispersion as 31pt talent. There are arguments like "Why we don't have Vampiric Touch as 31pt talent" like arcane got AP moved there, that would be more iconic. "It's useless in PvE, if you play good you don't have any uses for it". "Why we have evocation as 31pt talent?". "If you use it for mana you can't use it for damage reduction". "Why can't we have +%damage talent like Hunger for Blood as 31pt instead?"
Me myself find it pretty usefull when raids are still on progressmode. It's usually possible to time the use to gain mana and prevent some damage at the same time, saving healers some mana and gcd's. There are oh-shit uses, I have even got some firstkills just becouse dispersion gave few more seconds to kill the boss. It was useful on hc anub kiting, saph blocks etc. Granted thats really situational use, but it's all EXTRA included to already strong talentpoint. Progression is all that matters for PvE part, 31pt talent shouldn't be focused "for the time when you have everything at farm".
All in all, I love to have 31pt talent that encourages creative use of the skill, planning when to use it and why. I don't really want hunger for blood type talent as must have pve talent, ask rogues why if you don't know.
So in this thread, tell why you're against it. Give civilized opinions why you don't like it. Convince me with clear and sound arguments why it would be better to remove dispersion and get new talent instead.
