Using a word like "wise" in the given case is just as useful as the word "diligent" or "proper" for a domain. By nature, without stating it in a domain, you expect an accountant to be all those things. Saying we are "wise accountants" isn't really a selling point, because ALL good accountants are supposed to be wise, diligent, proper etc. Hence, I see little value in the domain, due to an unnecessary selling point, IMO
BUT, to add to that...if this was a "COM", my response to it would be different. If playing with an extension like "ACCOUNTANTS", that word really has to be on point and relevant (take Crypto "dot" Accountants as an example, biddable). Wise...not so much
