Read and enjoyed the write-up.
Side Comment on Natural Weapons:
They are briefly mentioned in the PH material on the Unarmed Weapon Group (p216), but all the support material (such as a definition in the Glossary) is absent. Currently they seem to be in limbo until WotC either cleans up the scraps or provides enough material to play with.
The gore attack needs to stay. The creature has it in the current MM and attacks with it; you can't very well take it away from players without putting a major hit on their "suspension of disbelief". You can control it, maybe build a few feats around it. If you take it out, you lose something important from the core concept.
In earlier editions "natural weapons" was the term used to define that the penalties associated with human unarmed attacks were not applied to the monsters with significant claw, horn, teeth, tongue, tail, etc. attacks. In other words, since "unarmed" attacks had significant game penalties, the term "natural weapons" was used to designate attacks by monsters that were not subject to "unarmed" penalties.
Personally I have difficulty envisioning how something with natural weapons is "unarmed" or how teeth, horns, and claws can be considered "improvised weapons" when they are what all the natural/bestial monsters attack with, but your mileage may vary.
"Natural weapons" is proving as elusive as "Stance" in these books.
"The gore attack needs to stay. The creature has it in the current MM and attacks with it; you can't very well take it away from players without putting a major hit on their "suspension of disbelief". "
No, actually, the Minotaur as a playable race in the back of the MM DOES NOT have a natrual attack (gore). As for the Suspension of Disbelief: please tell me why the Dragonborn in the MM can get wings but I, as a PC, cannot have a Dragonborn with wings (even at level 30)?
The answer is simple: Monsters and PC fucntion under different rules. Monsters get "Natural Attacks" and "Natural Flight"; PCs don't.
The rest of your arguement is valid....to a point. I still believe that the fact of the matter is this: Natural Armour and Natural Attacks DNE (DO NOT EXIST) for PCs in 4e.
From Khaalis:
"The current version of the race still includes a basic Gore attack, treating it as a melee basic “weapon attack”. They are also retaining the Goring Charge power."
Again, read your MM (pg 278). I do not see a Natrual Attack for the Minotaur (Gore) in the entry.
From Eldritch_Lord
"3) Crunch over Fluff. Powers are balanced on the assumption that a level X power can have Y effect, whether it's a magical blast, sword swing, fist to the face, or something else. The Power Description section actually states this time around "The given flavor is optional, change it if you wish." Thus, as long as a natural weapon has equivalent advantages and disadvantages to a regular weapon, it's basically a regular weapon, and thus nothing new."
The Crunch is that the Minotaur is now always armed with a Short Sword (well, almost a short sword; the proficiency bonus is 1 less). You can't take it away from him without clipping his horns (and if your Minotaur was in one of my campaigns and got arrested or imprisioned for any reason, that's exactly what would happen) and since he can use powers with his horns, there is no way to disarm him. Sure, a Dragonborn can use a 1d6 breathweapon 1/5mins, but a Minotaur is now the best hand-to-hand martial 'fighter' there is. No other race stands a chance agaisnt a Minotaur if both races are 'unarmed'. Heck, a Halfling has a pretty good chance against a Dragonborn, but a Minotaur will squish both. That definitely is a big advantage and I don't see the equivalent disadvantage to balance it.
Alright, before people start getting mad at me for continuously coming back to this point, let me say this:
If you (Khaalis) are simply trying to make a more robust version of the Minotaur, that is still relatively balanced, to use in a homebrew campaign, then I don't see a problem with your Minotaur as is.
If you (Khaalis) are trying to make a 4e legal PC race, then the Gore attack has to go. Period. I would tell you the same thing if you homebrewed a race with Natural Armour. It may be relatively balanced, but it is not 4e legal (as far as the current rules are concerned)
