Just pointing out:
Just as trapfinding is simply a function of the Thievery skill, It's quite possible that Ritual use is a function of the Arcana Skill. Only the Wizard and Cleric are trained in Arcana, and only they get the ritual ability.
Speaking against this would be that the ability to use Rituals was explicitely mentioned in the character sheet. I don't remember the Rogue class description on the DDI have such a special note for traps.
But my guess is that only spellcasters get rituals per default. Everyone else has to take a feat for it. That's something I would not mind, generally, though it would speak again ideas of using rituals as a base for non-adventuring activities (perform, profession, craft). (Though I never really assumed that this was a "core element" of the rules, and it's more something we - as EnWolrd - came up after the fact...)
For the original topic: I think there will be some considerably limits to how many powers people will be able can use per day/encounter. Otherwise, you would use your encounter powers the whole encounter, and never get to the basic attacks.
Still, there seems to be a significant difference between how many powers people have at all.
Wizards get to pick their dailies. Clerics have powers that use the same "slot" (Divine Challenging), but in turn get more powers known. So it's hard to guess how much powers people will have to choose from, and when they have to choose. (Each Level? Each day? Each encounter?)
