With all due respect, this is a cop out.
Other classes get serious upgrades, but you're arguing that paladins should just be happy w/ "flavor" and roleplaying?
I'm sorry, I'm not buying it. If other classes get substantial things that help them throughout an entire quest, then why should paladins be stuck w/ only a limited number of hits per rest? For "flavor?" For "roleplaying?" I'm sorry, it should be more substantial than that.
