Bobby, solid posts, except for the unsubtle ad hominem attack. Implying that Linde's problem is that this does not give him enough "POWAR!!" should be below our level of discourse.
That realms with a broad focus would be hit hard by this is a good point. They are often already affected by this in their class levels - I think that most guilders have some rogue levels or something. This removes casting ability already, because the casting level is lower than the character level would imply. For some regents, that must be a hard hit. Since it gets harder to level up, those different levels will hold you back for quite some time, though the diversity might be worth it. Hard to say, since fighter and rogue levels have very little direct impact on the realm level of things.
That it might hit some players harder than others, that it might nerf characters that do not need nerfing, should be a concern before rule changes are made.
(for the record, my character would have her power slightly boosted by this)
As for the second point, then it becomes a question of why we are bothering to make these changes. If we need to first split part of our character levels up, compare part of them to one table and compare the total of them to another table... it's not really simpler than reading the character levels and applying one table.
I think the reason that Bjørn introduced the skill table, way back when, is that it simplified things. Before that, skill bonus was a mix of stats, skill points, feats, racial bonuses, etc. It simplified things considerably.
Casting ability comes down to one thing: What is your effective caster level? This sets how many spells you can cast in a turn, what the highest level spell is and how powerful those spells are.
So, partially to my own surprise, I am actually against this suggestion in the end. The casting level system is already pretty simple, it only gets complex for sorcerers because they have to look hard at how many spells they can keep in their memory. If we want to simplify spellcasting, which is a worthy pursuit, we need to simplify how spellcasting works at it's core. Namely things like the 9 spell levels, of which only the first... 6 are necessary. The fact that spells are hard to balance, because caster level means the world for some of them, and next to nothing for others.
Right now, the simplest solution is to count up your spellcasting levels and use that number. If skills had been just as simple, I imagine we would not have switched over to the table for that at all. If a skill test was defined as rolling a d20 + relevant class levels, the same way caster checks are made, then... it would work fine as it was. Something like this table might work:
Caster | | Maximum | | Spells pr. |
Level | | Spell Level | | Turn |
1 | | 1st | | 1 |
2 | | 1st | | 1 |
3 | | 2nd | | 2 |
4 | | 2nd | | 2 |
5 | | 3rd | | 3 |
6 | | 3rd | | 3 |
7 | | 4th | | 4 |
That is for a wizard, a sorcerer would count one level lower. Which brings about another point, if we want to simplify spellcasting, then dropping the distinction between sorcerers and wizards could be a good idea. I would miss only having to prepare spell levels, instead of specific spells, but hell... it
would be simpler.
