On holiday at the mo but i will re-examine this when i get back.
The exp thing sounds like a bug though to be honest, definetely shouldn't work like that (more exp from lower level mosnters)
The base set is indeed very slow though, For a better speed i recommend tripling the stamina and focus score of the monsters.
The capture %ages can be configured manually for each enemy via the ACP. By default monsters have a 20% chance of being captured, 30% when they have <10% hp and closer to 5% when they have above 33%
In addition if a monster is a higher level than a player it will be harder to catch, lower will be easier.
As far as some moves seeming weak, thats because they have ideal ranges. Take magic missile for instance - the further away you are, the more damage it will do. at 6 squares it does 120% damage, 5 squares 100%, 4/3 squares 50%, 2/1/0 squares 10%
Magic attacks can usually hit from anywhere, but they tend to be a little less powerful to account for this.
Hovering your mouse over the move will tell you what the best range for it is.
Some of the moves at the moment have stats put in for balance sake, rather than a purely logical, coherent setup (such as stomp).
Currently i'm holding off on a new set until the manual is complete so we can tie the two in, but there are plans to create sets with different speeds and setting for different audiences.
Keep the concerns etc coming though, it's always good for me to hear which parts people are liking and disliking!
