Remove minimum of 6 chars for Zakum

Hi hi hello,

After getting Ravana's 2 character entry requirement revoked I think it is time to continue this trend. Zakum still suffers from a 6 char entry requirement, while a significant part of the community has now gotten to a point where 5, 4, 3, or sometimes even 2 characters suffices for the run.

Sure, there's an argument to be made for either nostalgia or somehow 'setting an expectation' (e.g. new players knowing that they shouldn't be tackling Zakum with a party of less than 6 people) but I feel like neither of those arguments really weighs up to the inconvenience from having to essentially bring sign mules to get your duo/trio/quad zakkies rolling.

Additionally, Zak is pretty much comparable to Krex (with regards to required party strength/hp), which does not suffer from a similar requirement.

As such, I'd like to propose removing the entry requirement of 6 signs.

Feel free to discuss below!

Kind regards,
Ainz
