Kaelik, I'm not exactly seeing an argument presented above. Are you merely angry that some people on the board consider the the Erudite to be better than the Wizard or Sorcerer?
Because I believe this thread is intended for the discussion of the power level (in comparison with Jaron K's Tier system) of the Erudite.
Tier 1: Capable of doing absolutely everything, often better than classes that specialize in that thing. Often capable of solving encounters with a single mechanical ability and little thought from the player. Has world changing powers at high levels. These guys, if played well, can break a campaign and can be very hard to challenge without extreme DM fiat, especially if Tier 3s and below are in the party.
Now going off that scale, I believe the Erudite is a tier 1 class. And it should have nothing to do with the power comparison between the Erudite and any other of the tier 1 classes.
No, I am mad that people think the fact that you can dumpster dive hardcore to match the cheese of Core Sorcerer makes a class Tier 1.
Tiers are and must be based on non cheese. If they are based on cheese then Here is a list of Tier 1 classes:
Wizard, Cleric, Druid, Archivist, Artificer, Erudite, Sorcerer, Favored Soul, Psion, Binder, Beguiler, Dread Necromancer, Crusader, Bard, Swordsage, Binder (without access to the summon monster vestige), Wildshape Varient Ranger, Duskblade, Factotum, Warblade, Psionic Warrior, Rogue, Barbarian, Warlock, Warmage, Scout, Ranger, Hexblade, Adept, Spellthief, Marshal, Fighter, Fighter, Monk, CA Ninja, Healer, Swashbuckler, Rokugan Ninja, Soulknife, Expert, OA Samurai, Paladin, Knight, CW Samurai, Aristocrat, Warrior, Truenamer, Commoner.
All of those classes are capable of casting any 9th level spell or lower at CL 9999999. That's enough to break the game.
Tier 1 is not based on which class has can dip, twist, and weasel it's way to the highest power level, because 90% of all classes cap at the same cheese level. Some classes can do it at lower level. That's it.
I have seen no special thing that a Sorcerer with less cheese can't do. You aren't going to convince me that Erudite is Tier 1 based on seven book cheese.
This is how you determine Tier:
What Tier is the Erudite without spell to power? Tier 3? What Tier is the Erudite without Spell to Power and meeting someone with Arcane Fusion and or Greater? Tier 3? What Tier is an Erudite with spell to power and Arcane Fusions but no retraining? Tier 2? What Tier is an Erudite with Spell to Power, also several other variants that replace Spell to Power, and retraining to use them all, and Arcane Fusion? Tier 1, but he has to spend XP out the ass. What Tier is an Erudite that abuses infinite training loops, and infinite power point loops and everything else previously mentioned: Tier 0?
What Tier is a Core only Sorcerer? Tier 2. What Tier is the still Core only Sorcerer? Tier 2. Core Sorcerer Planeshift? Tier 1. Core Sorcerer with Retraining and Planeshift? Tier 0. Sorcerer abusing everything? Tier 0.
Sorcerer wins 4 out of 5. It ties the other one.
I have a more powerful Tier 0 doesn't matter, because actually, everyone has the same Tier 0, Arbitrary numbers of Staffs of any and all spells emulated to an Arbitrary stat and Arbitrary CL, even 14th level ones if you care.
You have to tell me that in any game I am ever going to play there will be an Erudite better than a Sorcerer in that same game before I believe you that Erudite is Tier 1. Amount of cheese to reach power level X is important.
