Yup. Not only the powers should go on the chopping block; but the total number of options should be drastically reduced (be they power or whatever they choose to adopt.) In a recent Legends & Lore column Rich Baker admitted that 4e was at least a factor of 2 (in terms of numbers of powers) more complex than what they aimed for.

Finally, I removed the feats (since for the most part in 4e they don't provide special abilities), and gave the characters a +1 to defenses, attacks and damage per 5 levels.
With these changes, the game takes a completely different aspect.
I will admit that I am not bothered by the "encounter, daily" structure. It can all be framed in terms of opportunities. Sort of "authorial power" in the hands of the players.
It is the spirit of the game, not the letter of the rules, which is important. Never hold to the letter written, nor allow some barracks room lawyer to force quotations from the rule book upon you [...] YOU ARE CREATOR AND FINAL ARBITER.
