The problem I'm seeing with this whole discussion is people aren't talking to each other, just
at each other. IMO, the issue isn't if expertise is a tax but if it belongs at all in the first place.
It doesn't matter if you think the game math is fine. It doesn't matter if you think a character will or will not suck without an expertise feat. What matters is that Expertise feats are
vastly superior to all other feats. If someone said to you that you could either increase your salary by $10K per day or you could earn an extra $10K every time a month ends on a Friday, which one would you pick?
It's really as simple as that. The Expertise feats grossly overshadow the effectiveness of other feats. It's not about being "forced" to take the feat. It's about the fracturing of the illusion of choice. Feats should be balanced with all other feats so when player X is picking up a feat, it's a decision, not a no-brainer. You can tell me you don't need Expertise, and that's all well and good. But when you're in the Epic tier and your buddy is hitting 15% more often than you with all or almost all of his attacks your happymeter is going to be a little less full.
Is the feat tax? To those that feel/perceive/accept the math to be broken, yes it is because those same individuals believe a character will be gimped without Expertise.
Is the feat not a tax? To those that disbelieve/ignore that the math is broken it is not because there is no gimping of characters going on in the first place.
To me, I don't care if you call it a tax or not, it's still an overpowered feat that shouldn't be in the game.
See this is my main problem right here...you took 2 feats to INCREASE these things, but instead of calling it a bonus, you say the breath and like attacks are behind...
<snip>
Notice the same character that replaces those feats with enlarge breath weapon and the feat that adds radiant to the breath weapon has th oppisite complaint... His BW attacks have improved but not his holy symbol and weapon...
At the risk of being redundant, I'm going to dissect this a bit. If one character picks up Expertise with a weapon and an implement there's a good chance he/she's covering 90+% of all combat options. If someone instead picks up the feats you suggest to enhance his or her breath weapon, how often is that coming up in play comparatively?
It's not about broken math. It's not about gimping characters. It's about Expertise feats being vastly overpowered choices.
