Those players who hit the new cap within a day of seeing the level limit raised have truly obscene amounts of gear already (and I'm saying that as a character with some fairly profane amounts of gear myself). They have big amounts of greater and lesser essences just waiting for the cap to be raised. If you count the amount of play time that went into actually getting all of those essences, it's a lot more than one day of "regular" play.
Since those players often run quests in half the time that other players do (Star is seriously disappointed by quests that offer less than 1000 XP per minute while I'm pleased when I get 500 XP/minute in those same quests) and usually have far less down time between quests. The top 1% of the player base will do just about *anything* within a day of release. The rest of us are taking a lot longer.
I do think that the balance for the first 30 levels is great. You get to level quickly in crafting and when you get into the low to mid 30's, you finally start to craft some things that are useful. It would be nice to have those useful things at the same ML as their lootgen counterparts, but that's another issue...
The exponential increase in the number of essences required to reach the higher levels does bother me and it makes the 22,000 clicks method a lot more tempting. I don't like the idea of having part of DDO that works better with a keystroke/mouse click macro recorder than it works in just regular play. Part of the release notes makes me think that the 4 lesser/1 dragonshard fragment recipes are going away in 10.1, so the "carrot" of playing with a macro is going away. I'd like to see the "stick" go away too.
Maybe we could get the exponential increase in shards required dropped to just a quadratic function?
