Why should have anyone thought that Psionic Powers would provide material for Martial, Arcane, Divine or Primal characters?
That's the point, though - of course Psionic Power didn't provide support for those earlier classes. That didn't mean that this one product represented all development going forward.
No offense, but to use your words, I think comparing this is ridiculous.
Do you deny that HotFL/FK provide players with the needed base rules to play?
Not at all. What I deny is that HotFL/FK having the basic rules of play somehow means that it cannot provide support for PHB characters. And Heroes of Shadow, meanwhile, does not provide those rules - and can thus be used with
either the PHB or with HotFL/FK.
a) It is also a fact, that a player with only the PHB has absolutely no reason to buy Primal Power. But if you play a primal hero, you know it is supported in there.
Heroes of Shadow provides material for the Cleric... but not the Str Cleric from what I know so far and what I assume. Same for the Cha Paladin.
If your concern is that they should make it clearer which types of Cleric is supported, I suppose there is an argument to be made there. But to say that because it doesn't support the Str Cleric, the support for the Wisdom Cleric
doesn't count - that doesn't make any sense to me.
Again, looking at earlier products - the FRPG provides the Dark Pact, which only helps Charisma based Warlocks. Yet it still counts as support for the PHB, right?
This is not a valid point for my above definition of support.
And that definition just isn't a reasonable one, in my opinion. If I'm playing a PHB Wizard, Heroes of the Fallen Lands provides some 40-50 new powers for me to choose from, and some 20-30 new feats of use.
Arcane Power provided 94 new powers, and maybe 40-50 new feats of use. Now, what did it provide
exclusively for the Wizard, which wouldn't be of any use to the Mage? New Arcane Implement Mastery options.
Of course... that covered less than a page of new content.
What's the difference between the rest? I mean, powers are really the bulk of the character options in 4E. Sure, Arcane Power is providing
more content. But is that reason to actually dismiss the content in HotFL as not being support? Those powers are just as useful to the PHB Wizard. The absence of a single page of 'unique' and 'exclusive' content in the form of new class features... sure, feel free to miss it. But to say that, without it, no support is being provided... just doesn't ring true to me.
But it looks like that HoS indeed excludes Con-locks, Cha-ladins and Wis-clerics, while providing material for the other build.
And, again - I'm not sure it matters. The lack of support for one thing does not
cancel out support for something else.
The question at hand is whether HoS provides support for PHB characters. And, in the end, it does.
