When a friend convinced me to run a Kingmaker game, I gathered up a couple of other players, and due to their busy real life schedules and the short-term notice, I ended up making characters for them (although they did the RP work in terms of fitting a background to the character's stats, and as they're both seasoned roleplayers, they've done a good job making the characters come to life). The initial friend made his own character.
The problem is that I may have slightly over-optimized the characters I made - one is an angel-kin aasimar paladin, and the other is a tiefling diviner (foresight). Without boring you with the stat blocks, they're both excellent specialist characters - the tiefling controls the battlefield well and the paladin does reliable, significant single-target damage.
The other character (the player who initially asked me to run this game) is playing a dwarven druid. There's nothing wrong with the character, but it's not built to the same levels of optimization as the other two, and I get the impression that the player feels somewhat left out in combat. I've been doing what I can to make it clear that the party would have serious problems without the druid (for instance, survival rolls for getting lost, hunting and weather, and the actual map-making, since only the druid has knowledge geography). They haven't made it to the ruined temple of Erastil yet, but the dwarf is a follower of Erastil, so that combat should be a chance for him to shine.
The player has been talking about taking a level or two of monk (sensei) and feral combat training to have a good melee character in wild shape, but I honestly don't think that's the best choice mechanically, and it only going to exacerbate the problem.
Is there anything else I can do, in terms of suggesting character advancement choices to my druid player, or in terms of tweaking the actual AP, to make combat more enjoyable for my druid player? I hope that once they hit level 7 or so, the druid will catch up in power, as a full caster. I just want to make sure the player has fun until then.
