Slightly lost amidst yesterday's big Clvl 60 announcement was Bashiok saying that it would only be possible to put points into 7 active skills at a time.
This makes sense, in their "only let players do stuff that's helpful" interface system. After all, there are only 7 skill hotkeys, and if they don't think people can figure out where their sword went if they include a weapon switch hotkey, they're sure not going to trust players to put points into more skills than can fit into the visual hotkey display.
The controls-on-training-wheels aspect of things aside, I don't see any real problems with this. After all, you're not required (I hope?) to put points into 7 skills. You can just use 4 or 5 and load them up, or save some for later skill investment when you pick a 6th and 7th skill, or respec one or 2 of your 7 as needed, etc.
Some things can't be figured out yet, since we know nothing about where passive skills have gone, max skill caps, non-level up skill points, and the long term utility of low level skills. If skills max at 10, and we get no skill point quest rewards, then that's a very different situation than maxing at 20 with 5 +skill points from quests on each difficulty.
But in theory I'm not opposed to the 7 skills limit.
I hope some people who don't like it post, though, since I want to enlarge my thinking about the pros and cons of this change.
