Mythic adventures and the Automatic Bonus Progression from Unchained are two systems that I've been wanting to try for a long time now and I'm going to be GMing a new campaign in a couple of weeks and want to try using both systems.
For tanking the paladin is probably the best because of the self healing and I think they also have some spells that make the enemies focus on them like Challeng Evil. They are also good at doing damage, especially when they get to smite. After that the best is probably the barbarian due to dr, high hp and high damage
Casters: 1 cleric, 2 sorcerer, 3 wizard. Melee: 1 barbarian, 2 paladin, 3 unchained monk or fighter, im not sure. Ranged: 1 ranger, 2 slayer, 3 kineticist. I also like the arcane archer but thats a prestige class so i dont know if i should put it on the list. Support: 1 bard, 2 skald, 3 unchained rogue or ninja.
In the case of one enemy having both arms restrained in front of it it can still attack but with a penalty, when the arms are restrained behind it (the variation I usually use) it can no longer attack with those arms and when used on multiple creatures they both become entangled. Its not RAW but it makes sense
The animal has diferent stats and abilities so having a separate char sheet makes it easier, while the animal has its own initiative most people have it act on the player's turn since that makes the combat flow a little better and its HD is separate as indicated on the animal companion basic statistics table. I believe the table is on the Core Rule Book but it can also be found here: http://www.d20pfsrd.com/classes/core-classes/druid/animal-companions/
Something that takes place entirely in Tian Xia/Dragon Empires would be cool
Something focusing on fey and the First World could be very fun
Another Mythical AP or at least some modules would be interesting
An epic journey through several different planes (the Mythic sistem could fit very well in one of those)
Arcadia looks quite interesting as well
One other thing I would really enjoy is an AP where the action takes place mostly in big open areas so we can make some good use of mounted characters, personally I really like mounted characters but I seen to be on the minority
I know a DM that generally focuses heavily on role playing, dialogue, politics, etc, and his games tend to have little to no combat. One day he wanted to play a meatgrinder type game and the rest of the group seemed to know it but nobody told me that detail, so naturally I build a face type character, he was a halfling bard with high social skills but almost useless in combat. He died in the third round of the first fight.
In my group we have a house rule that if you confirm a crit with a natural 20 you can roll the d20 again and if you get another natural 20 you instakill whatever it is you are attacking, no need to roll damage (something similar applies to natural 1s, I once had a character die trying to ride a bicycle).
I have played in an all bard party before and it worked really well. Bards are a great class for this because of their vriety of abilities, they can melee, they can heal, they can face, they can buff, they can sneak,they can be skill monkeys, they can do anything really.
That sounds awesome, really want to try that now
