I admit it: I'm a stick in the mud. "If it ain't broke, don't fix it" is one of my mottos. I tend to reject out-of-hand changes that are made just for the sake of making changes.
That being said, DDO needed some change.
THAT being said, this wasn't the change we needed.
So, let's dig into the enhancement revamp; absolutely, it needed to be done, but equally absolutely, there is simply no justification for the way it was done. At a casual glance, I estimate that ~33% of the "abilities" in the collective trees are there simply to occupy space and force us to spend AP on them.
Now, you could just say, "We don't want you to be able to play a half-elf druid/monk unless you sacrifice the very synergy that would lead you to want to play such a character," but that is obviously stupid. The big question, then, is: Why did you think that having the attitude without explicitly saying what you are doing somehow makes it smart?
I like being able to access 6 class trees, too; I mean, you can't possibly actually take meaningful abilities from that many, so it's completely useless, but I suppose that it is nice to look at.
TL;DR: You need to take the filler out of the enhancement trees.
Oh, and fix the ladder bug already.
