I don't understand why you would make it harder on yourselves by not wearing proper PVE gear. It's not like getting campaign equiv is very hard, It might take 3-4 weeks of HM EC farming (class make up dependant)
I can understand doing it deliberately in pvp gear as a challenge but not bothering to gear up properly just reeks of laziness, especially since you've had 4 months to do it in.
I don't want to speak for anyone; so this is just my perception. A pvper can pvp 12 hours a day but just doesn't enjoy grinding the same pve content for weeks.
Similar can be said for pvers. Not all top raiders obtain the WH relics. It only takes about 30-40 WZs in a week or two.
I respect them all.
