Sorry, that is simply not true. One good tank, medium healer and one good dps can help the others run through it, sure. But even 6 monkeys with cymbals would have to grind their way to the power level. If you don't believe me, try doing House of Crom with a complete group of new players just turned premium (e.g. with Atzel gear or similar).
Even the mechanics (unless you link them by script) are not that easy to figure out (with common sense at least, try and error works most of the time). Add to that the average grinders wipe tolerance, i still keep to my statement, that House of Crom is not available for the majority of chars. And if i want to take you serious, there must be a serious gap in perception and power somewhere.
Give me an editor for AoC anyway similar to Aurora and i make you at least 5 minimaps and 3 new types of minigame rulesets in a week maximum. For new minis it might even be enough to copy/paste existing maps...add some spawn points and let the deathmatch or capture the hill commence...
Don't even get me started about crafting ...
