Could you expand on your underlying reasoning and your motivations here?
In other words,
why do you think a character should get to use all these rituals practically for free?
Before we can offer comments, we need to know what the real problem is.
Rituals are meant to be the filler for the "missing" magic in the 4E system that casters lost when moving to the Combat Only ability model. All of the non-combat magic that really defines a caster. A wizard is not just Magic Missile. The class assumes the use of rituals since Ritual Caster is a Class Feature.
However, ritual casters have to spend a LOT of money to actually USE this class feature. Not only do they have to Pay to learn most of their rituals, they have to pay fairly decent sums of money to USE their class feature. No other class than a ritual user has to pour money into the use of their class features. Why does the use of a utility like Comprehend Languages cost 10g each time it is used when it should be a defining class feature?
From what I have seen of in-game testing, this creates a disparity in the party. Any non-ritual caster sinks their money into the necessary magic items that the system expects them to have to make the math work. A ritual caster (if they want to use their class feature) falls behind on the magical gear they acquire because they have to sink money into their rituals.
If a 1st level ritual caster uses says 4 1st level rituals on an adventure they are automatically 40g behind every other member of their party toward that shiny new item. This gap continues to grow each adventure as the ritual caster uses more and more rituals.
I simply don't see this as balanced from a DMing perspective. This basically encourages ritual casting classes to ignore one of the class features that Should be a major defining factor for them.
Am I the only one?
What I propose isn't completely free access to rituals, but a limited way of allowing SOME free uses of rituals.
1) Allow some form of Ritual Material Focus that replaces the material cost of using some rituals.
OR
2) A feat that allows a certain number of rituals to be cast without a material cost.
OR
3) A spell point system that grants the ritual caster a "pool" of points that can be used to substitute for the material cost of rituals. This is the option I like most personally. This could be granted on a per day basis or a per level basis.
Am I even making myself clear? Writing from work always tends to be more difficult due to distractions.
