I love the idea but the power range is kinda HUGE.
You have a skill focus feat given as a minor, and then a +3 to one of your senses for skill checks also as a minor.
As for major:
You have a HIGH pre-req removing speed penalty from heavy armor, and an unspecified weight benefit (rarely necessary, almost never useful.
Also you have a level 24 Epic destiny feature as a major.
"Well, here's something important, my games run on a logic screws the rules system. If a character takes something, like the merit that allows them to carry more weight and wear heavier armor with little penalty, I will take that into consideration for other aspects of their character. In a completely mechanics based game, many of these are broken."
"However, if you play a game where your players will break these rules, you'd get laughed out of my games. Not to say your play style isn't valid, it just isn't accepted with us. Once again, DM oversight is key here... If you players make a Great Build, Mute, barbarian, tell them 'If you speak, I will shove a gigantic DM stop sign up your ass, cool?'"
"If a player is going to make my other players feel inadequate, or build a character that breaks the rules or the ambiance of my game, they leave. So if you can't play that kind of game, tweak this system or don't use it. I've said, in almost every post, this is a bunch of suggestions of how you might make a system like this, and things to add to it."
"Also... How is 15 Str or Con a HIGH prereq? Are you playing 4e? If ANYONE who uses Str or Con as a primary or secondary does not have a 15 in them, they better redo their ability scores... Honestly, the prereq based ones, are just the ones with which a prereq seemed simple and obvious to provide. For many of them, I just tell them, how can you make it make sense?"
"I have a paladin in the group who has an attention problem, which has granted her Inaction and Sluggish, flaws you would likely attribute to a slow (mentally or physically) character. Yet, she has them because she is childlike, and sometimes just isn't paying close attention. I also have a drow assassin who has a relatively high Con, but took Feeble because the shadow energy drains his Fortitude."
"This entire document is notes, a base system and a bunch of ideas, so if they don't work, write new notes. If the system doesn't work for you, either you should wonder why, or don't use it."
