It will be the opposite around unfortunately.
Average a trophy per 2 year is the footnote, 12 years (and counting) without a league title will be the main script.
Not everybody start following Arsenal before or during the invincible season. A lot of fans, including me, follow the team after that; and lot of fans do not have a chance to see Arsenal winning the league, have a taste of being the champion.
The league title, is the measuring bar.
