FrankTrollman said:And Polymorph Any Object lasts forever - so once you get access to an 8th level spell (even from a scroll) the template is a waste of time. So the template has a time limit. At 7th level and below it renders you subject to Cloud Kill and Color Spray - making you essentially krill. At high levels the template does nothing at all.
Is it so awesome in the mid-range high levels that it justifies the loss of three levels off the high end of your character both now and in the future when it doesn't even get you anything? I would submit that it does not.

PAO doesn't always last forever. In this case, I believe it would last 1 week: +5 to the duration factor for both being animals, and +2 for them having the same intelligence, for a total of 7. Also, it can still be dispelled, and won't work in an AMF
To be honest, though, I think that the bigger problem in the situation you paint is the spell, not the LA. A level 8 spell that allows long term/permanent changes in a character's race, creating a free way around LA? If this spell is allowed as written in a game, there's really no need for using ECLs and LAs in the first place (and I think most people will agree that having a monstrous race needs LA).
I realize that it may be a bit of fallacy to consider it, but do you think the +3 LA would still be underpowered if PAO was not an option for obtaining the template?
