Support page isn't too different from an AP page though. Probably just ditch the AP and get some armour instead.
you need dat 1 crit rune doe
i have only 3 support runes
a tanky page: armor quints, armor reds, flat hp yellows and flat mr blues for like leona and sometimes thresh
a thresh page: armor quints, ad reds (and 1 crit rune), flat hp yellows and flat hp blues
a weird ass sona page: 2 armor quints, 1 ap quint, hybrid pen reds (and dat 1 crit rune), hp yellows, and like 5 flat mr blues and 4 flat ap blues
i have no idea what that sona page is supposed to accomplish lol
i don't think that's any good on sona, much better on someone like janna that just doesn't do much risky stuff. on sona you'd prolly need either more mr or some mana regen instead of those ap blues.
i'll prolly change that now, tho i really like the extra ap on nami
i hope they do a 2x1 runepage thing soon
