0 confusion because p2w is a binary. Either the game has purchasable power for everyone or not. As discussed I don't have purchasable power. As to your brothers since I'll actually address points instead of just calling you confused. The gold is being used to catch up to current content, quickly leveling professions and legendaries(which are gated by soul ashe/cinders more than gold) only help them return to participating with the rest of the community on the current patch. Accelerating yourself to the current content is not p2w.
WF raiders have the commitment to the game and the time investment to have the gold to afford BoE's if they want it. WF guilds spend all that gold and have deals with their raiders on how they plan to make gold and grant boe's as quickly and efficiently as possible. My guild which is not WF and I don't know of anyone buying tokens can afford all the boes they want on new patch launch. The proper question is "Can a guild buying tokens guarantee an advantage over a guild that doesn't". No, they can't because anyone that wants to partake in that race has the ability to make the needed gold ahead of time.
You gain no advantage(power or acquisition system) other players don't have access to by paying gold. The advantage for p2w must be universal. If you can tell me what I would need to buy for a guarentee'd power increase on my main step by step I will purchase it and the equivalent for you or any player you want.
