Looking at the costs of spells, I couldn't help but notice how high they were. If some one wanted to make a pure caster, at starting level (30 SP) they can only have four level one spells.That is unless you play a race that has an advantage that lowers the costs of spells, and even then that only allows you to buy one additional level 2 spell. This is a huge discouragement to anybody who hoped to be a caster. Not to mention how much this would hurt available healing in the game.
Also, you claim that there won't be any cookie cuttering, but with the high costs of spells, I can see people who want to play certain types of casters sticking with the races that get to buy the spells cheaper. It costs 128 SP to buy a full four column, unless you are one of those races, which lowers the cost to 93. A saving of 35 points is pretty major, and in my opinion anybody who wanted to play a dark caster and not play a demon is crazy etc.
Now, maybe this is intentional, maybe you want to down play the importance of spell combat and limit healing in the game. Just saying from a player's stand point, and a seasoned larp caster, this really sucks.
