Hi all,
Thanks for all of your input
Yes, most of the problem is thinking they 'need' an 18 in their primary stat, then still wanting the other abilities relatively high (especially those that help their characters survive, like dex and con)
We usually generate stats by rolling, but I'm fairly relaxed about what they can reroll, and I've previously allowed a certain amount of choosing what stats they want and going with those. Yes, I do realise I have brought most of the problems I'm having now on myself- but this kind of thing matters a lot less to me when I'm writing the adventures myself because I can take the higher abilities into account when designing combats.
The point about carrying capacity is a good one- at the moment they all have bags of holding/handy haversacks so we don't really worry about it too much. I'll look through their sheets and see how much difference that would make.
One of my players has now decided he is not playing at all due to 'all the restrictions'. As well as the PB, I've limited them to PHB classes only, dropped action points, taken away the free regional feat I was giving them at first level (although they get a free trait if they come from the Cauldron region), and dropped a house rule increasing skill points for some classes by two per level. I've made them aware that treasure levels will be lower, as we're running prewritten adventures, so they'll get what's in the book - at the moment they tend to be about one level ahead of the DMG in terms of treasure, since I have a tendency to give out slightly too much. This player tends to gravitate towards more unusual class choice and had previously decided he wasn't playing due to the PHB-only rule, then changed his mind, so he may change it again.
Of the others, one is supportive of the lower power level, and I think another is warming to the idea, and would probably be fully on board with the rest of the restrictions if I were to increase points slightly. The other two are unhappy at the moment, but I'll discuss increasing the points to 30 or 32 with them tonight and see if that helps.
