"Whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune, Or to take arms against a sea of troubles, And, by opposing, end them?” You know, as the quote continues, it becomes more apropos. I knew my undergrad degree in English Lit would come in handy sometime, somewhere.
The question might have been asked: "Is a kit with PE in the box, not a BKB kit?" In almost all cases, the answer would be, "Yes, it is not a BKB kit; it is a regular category kit."
As pointed out multiple times by multiple folks, the BKB concept is simple. But, this being IPMS, there has been an immediate reaction, boiling down to --"But I want to build it the way I want to build it". The reply is "Fine. Build it the way you want to build it. Then enter it into a regular category." The counter we hear is "But I don't want to enter it into a regular category; I want to enter it as a BKB. So, there should be a waiver to add/change/delete/modify/adjust the rules. These are my really good reasons: ________________"
In a serious vein, I think part of this reaction is (again, already pointed out) due to our history with OOB ... where the slope became slippery and some slid down it. I predict that appeals for exemptions from the BKB rules will continue in the hope that exemptions will again be granted. And they will continue until the BKB rules are enforced and become routine, or BKB is modified and becomes OOB Mk 2, or until BKB is eliminated.
