A good swordsman knows the tricks with swords. You seem to be implying that proficiency is enough to declare the concept achieved, when that would only be true in a relative sense when comparing with non-sword users. In short you can not claim your character is a good <insert weapon> master when you clearly are lacking the feats regarding that weapon.
I don't agree with that. There's a difference between an undisputed master that can best anyone in the realm, and the guy that best 90% of the people in the realm. The Paladin can easily be the latter without sacrificing much, but for the former he'll have to sacifice a LOT.
By the same token though, there's a difference between someone who spends every waking moment training with their weapon of choice in order to become the greatest swordmaster in the world, and a servant of a deity that has to split his time between prayer or worshiping his god and training with his chosen weapon so that he can enforce his god's will through strength of arm. The former is a Fighter, the latter is a Paladin. This is what I meant when I talked about the third ""But why can't I do everything" build. The Fighter's schtick is to be the undisputed master of a particular weapon, or weapons. But you want all the expertise of a Fighter with all of the divine power of the Paladin...but you don't want to sacrifice for it. You see the problem?
Whenever someone talks about the Paladin multiclassing, that's more ammunition for the argument that the paladin class doesn't measure up. You shouldn't have to leave the paladin class to be a better paladin. For the record I'm aiming for Champion of Order - my character will be a good swordsman (not great btw - that's fighter territory).
So you're going to be a good, but not great, swordsman? Then why is it necessary to have HBO and Heavy Blade
Mastery? As for the multiclassing thing, that's bunk. This system is muc less about the "class name" and more about what role and abilities you want. A Paladin/Fighter is really just a Paladin that's concentrating more on the martial skills, at the expense of some of his divine powers. Rather than detracting from "what a Paladin should be" it's actually representing one Paladin's shift to more of a focus on martial abilities when compared to his peers. He would still go through life in the game saying "I'm a Paladin", not "I'm a Paladin/Fighter".
And let's be clear, before any feat issues are taken into account, the paladin is suffering from MAD. Str for basic attacks, Cha for DC, Wis for healing/riding effects, and Con because you'll be getting hit a lot. The plain vanilla guy is wanting a minimum base 16, 14, 12, 10 - or 16 of 22 points, right from go.
I've covered the human racial traits. Basically the single boost and 3rd at-will do not make a Paladin great. I'd put Humans behind Dragonborn & Half Elves, and in competition with the Elf & Dwarf for 3rd place. This is not what the human write up indicates.
Frankly, it feels like the Paladin was rushed out there rather underdone.
Again, there's two builds here. The book specifically tells you that certain stats are more or less important depending on build. By your definition, plenty of classes are MAD. Take Fighters, for example. They STR to hit, WIS for Combat Superiority, CON for hitpoints and survivability and then a concentration on another score depending on their weapon choice. If that ability happens to be CON or WIS they can mitigate it, but if they want to go Heavy Blades that means they need DEX, and a
lot of it.
That's 4 abilities they have juggle. How is that any different than the Pally? Fighters that are concentrating in particular weapon groups like that need to make some decisions about how to split their stats too. My Dragonborn Axe Fighter that's going Inner Dragon, for example? He's going STR/CON with an 18/16, which means that I had to drop WIS down to a 12. It'll only ever get up to a 14 or 16, depending on if I put any points into it beyond the +1 to everything per tier. This means that Combat Superiority is relatively weak for me, but I did it because I need to qualify for some feats and I want to actually be able to hit with the Dragon Blast power I'm picking up with my PP. So it's not like the Paladins are the
only class that have to juggle, everyone does. You can't be good at every single thing that your class does, that's just not how the system works.
As for your complaints about Humans...well, they're typical of most any class that you use Humans for. Most people don't have a great need for a 3rd At-Will, although it ROCKS for Wizards. People also miss that extra +2 to a second ability score, but then you gain in the fact that all your defenses go up by +1...which, when you think about it, is actually a pretty good ability for a Paladin.
Lastly, look at Martial Power and what that did for the Martial classes. There are tons of class specific feats, many of them exclusive to Humans (technically Half-Elves too). There are also new builds, new powers and new At-Wills for every class. While yes, it would be nice to have 3 STR At-Wills and 3 CHR At-Wills for each build, no class got those (see also: Cleric and Warlock for Human 3rd At-Will issues). If Martial Power was any indication though there should be some new At-Wills for each of the builds, thus giving your 3rd At-Will option.
So no, I don't think that they rushed it and broke it. I just think that you have unrealistic expectations as to what the Paladin should be capable of. When you compare it to the other dual or multi-build classes, they have the same issues as everyone else.
