I am concerned that the new human, at a very high level, is too much stronger than the human is, at a moderate to low level.
The current situation, as of today, rewards attendance rather than skill and thoughtful play. In effect, a player who has been playing for a long time, but badly, and accumulated a large number of experience points over time, due to persistence, is now going to be vastly more successful than the player who gets the most out of limited resources, in challenging situations.
Having an advanced level increasing the percentage of successful outcomes is not unreasonable, but the gradient, as it stands now, is way too steep. Increasing the success rate by a few percentage points, instead, would keep the playing field relatively level.
To me, it makes no sense that the human/elf/dwarf are potentially stronger and more dangerous than dragons are. Dragons should be defeated by strategically using a combination of scrolls and potions that are in short supply, and are likely to be used up while there are still dragons to deal with. It should not be the case that predictably repeated feats make it possible to clear a room without depleting supplies of scrolls and potions.
If the player finishes a game with lots of scrolls and potions still in the inventory, then the game was simply too easy–a waste of time that is winnable, even after making lots of mistakes.
We votes that today’s situation is simply silly, and needs to be dialed back.
Increasing dragon health to 4 should be out of the question, as it leaves behind the majority of players, and all newer players, who are struggling to compete while using lower-level heroes.
As I pointed out in an earlier thread, the best (simplest and fairest) way to make it possible to deal with greater numbers of dragons is by putting magical objects (such as altars and mithril-like objects) deep in the lair, where numerous dragons need to be slain, in order to find them.
When increased skills are attached to the heroes, and the discrepancy between an experienced and inexperienced hero is so large, then the game rewards attendance rather than skill.
Just my two cents. :)
