It is tedious to complete hundreds, or thousands, of Tasks one at a time or a score at a time. How can it be wrong to remove tedium from the game?
Well the structure of the game offers an answer - as you progress through the VIP levels one of the benefits achieved is to cut down on that time and tedium - first by allowing individual tasks to be completed in a single click, then a dozen or more, then a hundred at a time and there is talk of it becoming a thousand at a time. Using an autoclicker undermines this part of what advancing VIP level achieves and sets the user effortlessly on a par with a competitor who has invested the time and effort to advance VIP.
This sort of game poses a challenge to patience and persistence and, curiously, quite a bit of the satisfaction from achieving particular bits of progress comes from knowing the cost in time and patience. I recently completed the level 9 Skald achievement at a cost of nine hundred name changes, each taking a number of clicks. Of course I did a few at a time every now and then over a period of months; approaching the last few clicks required was satisfying because of the persistence required to tackle the first few and the countless clicks in between.
When you watch one of the elite gamers it is their ability to balance numerous priorities and translate their decisions to their deft fingers on the game controller at lightning speed which arouses admiration, of course autoclickers are not allowed in top level gaming just as use of a computer destroys chess as a game.
Of course those who come here to buy pixels will have no understanding or sympathy with this - assuaging impatience is what they seem to want. But that is an altogether different activity.
