OK, BUT if you sat down to a game and the DM wasn't house ruleing the BW would you tell other PCs not to play there Dragon born character???
Or to spin this back around...if you want to take expertise with every character by level 12 cool, more power to you have fun...but when you say others should (even when they choose not to), or that DMs should give them out free (if the DM didn't want to) or even try to push WotC to change it when you KNOW there are people happy with out it...then there are problems...
I have a fellow player who thinks like an optimizer...he always has a min 18 starting stat to attack, he never take multi attack stat powers, and he always has +3 prof weapons...he also always has the NAD uppers, and expertise. How ever we have never seen him pull away from the pact in usefulness....
[sblock=going back an edtion or two] We in my group have had alot of problems over the years of one character domanating becuse he was built 'better' from my characters of grant and antra in 2e, to my firend paul makeing an abjurer in 3e...
we call them 1 man parties...becuse alone they could bring 70+% of the power of the rest of the group...
in 4e even the most optimized character is still 'just part of the team'[/sblock]
Just because I will not tell someone how to play their character doesn't mean I won't inform them of any potential pitfalls in their choices, if I am unsure if they are aware. Particularly since many of my friends would have lesser system mastery than I, were I to engage in a F2F game, I would let them know of potential issues if the DM was not addressing them.
I will not say, "Don't play a Dragonborn", I may say, "As a not, if we ever get to epic levels, you may have trouble hitting things with your breath weapon, due to XYZ Math rant"
I will tell them I highly recommend they take X feat as it is mechanically superior and explain a bit about why that is, if they are interested, but in the end I would leave it up to them. Just because I should not tell them what they 'can' do doesn't mean I'm no longer allowed to give advice.
Just because the DM doesn't WANT to adjust that math, doesn't me he should not. He's allowed his choice, right or wrong. If I feel he SHOULD, I will suggest/recommend it. If he does not take the advice, I may be disappointed, but chances are I will still want to play. I won't pressure Wizards to do anything, because I know my lone voice crying in the wilderness is meaningless, but if I feel my voice may correct the error, then I will for d*** sure make my opinion heard.
I am not certain the math is very off, but the inclusion of a similar scaling of Racial powers to Implement expertise in those racial feats tells me that something is off. It also would prompt me to encourage a DM allowing such races in their campaigns to look into adjusting racials such as the Dragonborn's to follow that trend, due to how it appears to me.
