Strength and the Kitty....Follow

For Kitty, while leveling, I rank Agi & Str about even and then stam afterwards. I always found that if I was in Kitty, I prefered to maximise my damage. If I was in cat and running low on health, then I should probably have been in bear form anyway.

For Bear, Stam was #1 then Agi & Str. Strength becomes less important once you start tanking, but while leveling you still need to be doing damage to the mob you are trying to solo.

99% of the time, 1 point of AGI will be better than 1 point of STR for maximizing dps.

I think this is how stats affect a kitty:
1 AGI= 1 AP + 1 critical rating
1 STR= 2 AP


While stam is always good, the point of a dps is...well, dps. While stam is never wasted, it's more important to concentrate on other stats first. Stam is mostly useful for soloing or if you plan on being a backup tank or something.

Here is what I believe the order of desired stats is:
AGI > hit rating(to cap) > STR > STAM

I would give up 2 agility and 4 stamina for 16 strength, yes. Of course, it depends on your other eq as well. Overall I'd prioritize agility, but the example you cite is a pretty big gap, and strength does matter too.

I generally wear twice as much added agility as strength, and that works well for me. As far as stamina goes, I stack it heavily because I only wear one set of eq for solo play, but if you've got a separate kitty set, it shouldn't be as big a priority for you.
