(re my complaint about Intimidate being based on Cha)
I expect to see something very similar to the Duelists Panache... DP allows a rogue to apply dex as an additional boost to athletics (why isnt climbing have a dex emphasis).
Could be called Fearsome Might?
(somebody presented a fighter utility idea and called it Knuckle Cracking to do the same thing if I recall correctly)
Sure, and this is a good idea, as it gives a better reason for the Str types who get Intimidate as their only social skill to actually take it.
That said... I do think this is a design flaw, and a case of some of the design lagging behind the concepts involved.
One of the big advantages to 4e overall is that it avoids marginalizing characters.
Everyone gets to fight. Unlike 3e, where Str and Dex were the fighting stats, in 4e, they may be the -default- fighting stats, but between classes with melee attacks based on every single one of the 6 attributes and the excellent feat Melee Training, everyone gets to play.
And, of course, skill challenges are conceptualized such that everyone gets to participate if they want.
Even in microcosm, there are some nice bits of pseudo-redundancy here. The mobility/stunt skills are Athletics (Str) and Acrobatics (Dex), so anyone with either stat can have a way to move around in non-obvious ways, even if the particulars are different.
However, in social situations, we're back to single-stat land again, unfortunately. Which is a big shame, given that what this means is that when you're in a social situation, the mechanics are telling you (if you're not playing a high-charisma character) to shut up and let the people with social skills talk--which in those situations is every much as bad as telling the 1e thief that this is a monster, not a trap, so he should sit back and let the fighter handle it, or to have everyone sit on their heels and let the rogue and druid explore the dungeon for a couple of hours. Yes, you can construct skill challenges that allow options other than talking -- and, of course, clever players can work Int-based knowledge skills into a conversation and try to substitute Arcana or History for Diplomacy or Bluff. But when you get down to it, players being left out of the conversation is still a very big deal--moreso when effectiveness in combat often means -not- putting any points into Charisma if it doesn't do anything for your build.
Moreover, having all three different (3, in fact) social skills under Charisma involves huge amount of redundancy. Clearly, the best of the skills for social situations is Diplomacy. It's nearly always applicable, and extremely flexible in approach. Bluff is a good complement -- and of course has some good combat applications. Finally, Intimidate is the social skill you don't want to have to use -- it's got several interesting (if usually to be avoided) combat applications, and has an entire set of fighitng abilities that require it, but both by flavor and typical challenge design, it's the narrowest and worst of the social skills.
So, what we end up with here is that anyone decent at social stuff has a high charisma and Diplomacy and/or Bluff--and nearly all builds with a high charisma have Dip/Bluff as class skills, and Intimidate is hard to get to a high level -and- is the weakest of the bunch.
Now, what if, rather than going with "Cha = social impact, so all direct social skills go under Cha", the three skills had been placed in different stat trees? Drop Intimidate in Str (or Con, as how "tough" you are), Bluff as Int (coming up with good lies as opposed to being generally likable) and keep Diplomacy under Cha. That way, nearly everyone would be able, if they wanted, to have a good score in a social skill -- but your class would constrain -how- you interacted with people rather than telling you to shut up please and let the charasmatic people talk.
An interesting alternative would be to have an even more direct parallel to the class structure (for AC/attack) -- have classes that get off-stat social skills often use alternative skills as basis for those skills. So fighters would get the feature "use Str as a basis for Intidmidate", Shamans would get to use Diplomacy via Wisdom, and so on.
Either way, it's a damned shame--and something that's going to constrain my choices whenever I'm not ok with playing characters that have to shut up and let the good-looking folks talk.
Hmm. I think I have a blog post here.
