Isn't there a cap for speed? I wouldn't know since I didn't really use it at all. I thought they capped it in the past.
for 1100 speed gloves cap is 93%
for 1220 speed gloves cap is 94%
for 1400 speed staff cap is 95%
so right now you can have 20% on lv 55 legend weapon and 8% on hat with rare dogiball
so 40% speed through weapons + 40% buffs + 8% hat = 88% so 5% missing and that's exactly 3x kaioken
so as dende / poko you won't reach max atk speed but still alot faster than crit
But you won't see any speed parties right now (I'm trying to make one but 8% on hat is fking hard) you will see speed parties on lv 60
