League of Legends before 2017 rune update:

You could literally play Syndra with cooldown reduction quintessences, cooldown reduction glyphs, cooldown reduction marks and cooldown reduction seals.

You could play Syndra with full attack speed. You could play Syndra with full AD runes. You could play Syndra with full AP runes. You could play Syndra with full AP/lvl runes. You could full tank Syndra with armor quints, armor seals, armor marks, armor glyphs, absolutely cannot die.

Meanwhile playing Syndra post 2017 rune change:

Your only options for what Syndra mid can go are:

2x adaptative force runes, 1x adaptative force rune and 1x AP rune

1x Flat HP +65, 1x hp/lvl HP

Incredible, that's what you voted for, you fucking imbecilic NPC goyimslave retards.

Now that the dust has settled, why did the rune rework flop so hard?
