Probably if you Play a lot 1 or 2 years to be Realistic if you play some days of the week but... If you complete your quests on power +130 and use your XP Boosts. Probablly in 5-7 Months BUT PLAYING ALL DAYS. Good Luck(In My case It took me 2years and 8 months to complete it)
With ALL items you mean BANNERS PICKAXES LOADING SCREENS AND LOBBY MUSICS and STW STARTER PACKS(I don't have all)AND the FOUNDERS REWARDS(I don't have them)?
