Well inquisitors get teamwork feats as well.
But we have a ranger in serpents skull that we literally couldnt figure out what to do with his feats, he seemed really to have all he need
(we could have gone the *yawn* power attack cleave route if we really wanted another one of those) so bot he and his wolf companion took paired opportunist, and the wolf has greater trip.. seems to work exceptionally well.
Apart from picking team work feats for you and your animal companion, there is lookout which is amazing for any divination specialized wizard, and his party. Apart from that I feel they are kinda meh.
Just remember that you need to boost your animal companions INT to 3 to be able to pick team work feats for it.
I was thinking about this the other day and couldn't really decide... on the face of it, it seems that some of the feats just plain suck ass, and all are situational... the one offering flanking seems and the one improving shield protection seem best for a Cav to take but am interesting in hearing from the community which they would favour... and if they are even worth it at all as NON caviliers?
I am playing a samurai and one of our party is a monk. We are using the outflank teamwork feat. The monk uses his superior movement to get into flanking position, while I use mounted combat at close range for large damage. It was been working well as the +4 to hit is causing more attacks from flurry of blows to hit, and it also helps with my attacks as I keep power attack active most of the time. I have the furious focus feat for my first attack, but subsequent attacks on a full attack option are boosted nicely.
Our two characters work well together, and we will likely add another teamwork feat before we are done.
