I don't think the discussion here is about weather the cap should or should not be increased at all (clearly that is not what is being discussed), but weather it should be increased frequently or rarely? And to that effect what value of time are we actually talking about.... It's clear from all this arguing and the thread before it that an actual number value needs to be assessed.

The question is how long should it be before cap increases? Do you have a preferred range? 1-3 years? 3-5 years? or is your idea more specific? 6 months? Can you provide objective reasoning as to why it should be as long as you think it should be? These are the questions that would make a difference, not this constant bickering.

BTW defining to people what things like Horizontal Progression and Vertical Progression actually 'are' and what they 'do' is not only partially subjective but totally insulting considering nobody asked you, so you must be assuming ignorance.

Here's my answer the gap should be 3 expansions wide at least with an exception for the first cap raise. I feel that this assessment is sufficiently appropriate because it provides ample time to increase complexity before raising the roof to allow more space to add even more complexity. If the roof is being raised to frequently then there is never any complexity to enjoy as there is enough space for all the elements to stretch out and breathe.

The average 'successful' mmo has a lifespan of 8~10 expansions (I'm talking about games like ffxi wow eq ultima-online DaoC) so if the roof is raised 3 times in 10 expansions we have a rate of vertical expansions of 1/3 (with a remainder of the first cap raise) and a rate of Horizontal expansion of 3. the product of which is the happy number 1.

This is just my opinion and clearly more horizontally inclined than vertically but it's my assumption that that isn't at all what we're really trying to argue. We're all smart enough to know that we need both its just at what rate and values do we need them how much should they lean to which direction, i doubt anyone here is so naive as to think the game should raise cap every 5 months or never at all.
