If my suggestions have merit on their own, then the merit is there despite my own vested interest in it; and if not, then the merits are not there, again,
despite my vested interest in the subject. The suggestions' worthiness is completely independent of its messenger. As such, I do not see how the fact that I am championing my own cause bears any weight on the suggestions made. Of course I'm going to champion my own cause--just as anyone else would champion their own.
To answer points you have made in specific, though:
Charm Person is a first-level spell, yes. However, Charm Monster is a fourth-level spell. They would
both be impacted by the changes, along with Charm Animal and Charm Plant.
The Enchantment/Charm (3.x's Enchantment) school prior to 4e has always had a great number of "save or suck, save or die, all or nothing" spells. As you point out, one could argue that Charm spells do, in fact amount to encounter-ending spells even left as-is, "save or die"--if one were to be metaphorical enough about what "save or die" means . The current "daze" effect still prevents any action whatsoever for the duration of the spell (which, in ALFA, is PnP-standard at 1 hour per level) anyway.
Outside of DM intervention, that is what Charm spells are, currently. Even with the proposed changes, this is also how they would remain
unless the opposed Charisma check (which
is PnP-rules) occurred. With the opposed Charisma check, they could be convinced to do something they wouldn't otherwise. The first line of the Charm Person spell's description reads that "This charm makes a humanoid creature regard you as its trusted friend and ally (
treat the target’s attitude as friendly)"--all of the other Charm spells have similar wording. The DMG defines the Friendly attitude as wishing the person well, and includes possible actions like offering limited help, advocating, chatting and advising.
This is, again,
without the opposed Charisma check. What about
with the opposed Charisma check?
Q: Dear Sage,
What exactly is the limit to what you can 'persuade' a charmed enemy to do with the charm person spell? How trusting of the caster is a charmed individual?
--Dave
A: The spell description for charm person indicates that the target’s attitude toward you becomes “friendly” as defined by the Diplomacy skill (PHB, pg. 72).
Thus, a charmed enemy wishes you well, and will chat, advise, offer limited help, or advocate for you.
The spell suggests that you might convince a charmed fighter to hold back an onrushing dragon for a few seconds, but that’s a pretty extreme example and would certainly require the opposed Charisma check described in the spell entry.
A charmed enemy doesn’t automatically trust anything you say, but it “perceives your words and actions in the most favorable way” (PHB, pg. 209).

So by the official 3.5 Q&A, Charm spells' subjects are
baseline friendly--and you can do the opposed Charisma check to move them toward an action more in line with
helpful--as an extreme example, holding the line for a few seconds while you run away from the dragon. (A far less extreme example: previous Dragon Magazine articles and previous AD&D editions stipulated that a charmed subject would try to halt a fight by defending its "new" friend against its old (using the minimum amount of violence--subdual could cover this) and generally trying to defuse the situation. Its new friend is still a friend, and it wants to keep
both its new friend
and its old.)
Balance concerns could be that the suggested spell changes would make the Charm spells too powerful for their respective levels: however, note that
any target in combat gets a
+5 bonus to its saving throw already; and also note that, again, an opposed Charisma check is
very swingy compared to a saving throw with a set DC. Moreso when the caster does not have a high Charisma.
Most non-specialist enchanter wizards in PnP and organized society (RPGA, Pathfinder Society, etc.) play probably don't bump their Charisma score up very high. I know Charisma is often a dump stat with several of my PnP gaming buddies. But enchanters are
supposed to be a bit more Charismatic than other wizards, and this gives them a reason to be so. The suggested changes actually benefit bards, favored souls, sorcerers and warlocks more than it does most wizards, being Cha-based casters of one stripe or another. They also benefit these casters
more than they benefit
me (but that's beside the point), and I don't really see it as being that big of a balance issue even then--the highest Charisma modifier I've seen on someone so far is +5, and that's not that sizeably different than the +3 CHA a wizard can get without even skimping too much on other vital stats.
