In general, I think that the game is already too difficult and the developers should work toward making the game easier, not the opposite.
We do need to hear more from people like you to gauge the difficulty of the game. A lot of the players around here are veterans that can beat hard difficulty dungeons without breaking a sweat, so we really can't speak for the entire player-base. (Though if the hard levels get substantially easier, we'll probably need a new "very hard" intermediary difficulty between hard and vicious. The gap between the hard and vicious difficulty levels is already quite enormous. Way bigger than the jump from normal to hard)
Also, some classes are really not fun to play: for example the transmuter. I don't understand why mana regeneration from endiswal makes some monster to regenerate as well. Transmuters should have normal mana regeneration also.
The Transmuter was horrendously overpowered a couple versions back, which was why this change was made. This class has gone through several iterations already and probably will see many more.
Deities are a nuisance most of the time: some are straighforward like Taurog, others are very difficult.
There is no information about what actions will penalize you and what actions will award you some piety, also there is no information about what punishment the god will inflict you.
There is the Wiki, which is updated by fans regularly:http://www.qcfdesign.com/wiki/DesktopDu ... =Full:Gods
Scout Altar and Starting Piety are redundant preparations now that altar auras are in.
Not redundant at all. The sparkles don't nearly add up to 25 piety, nor can they direct you as to the location of the alters so you can explore in their general direction. The whole point of these preparations was to start worship early or grab your first boon early without expending too much exploration resource. I can understand that you didn't like these preps (they certainly were too powerful, IMO) but the recent sparkles change is very minor by comparison and its role isn't even remotely similar to these two preps.
I should also add that scout player is now the only worthwhile temple preparation. Holy Diver, and Indulgence are largely worthless, and always have been. Now that piety is removed heretic might be marginally worthwhile, but your odds of actually finding the deity you want are abysmally low...
