Lichbane/spellblade has a cooldown of 2 seconds and not 1.5 as the tooltip specified.

I was doing some theory builds with Lucian and was testing a specific combo. I know Lucian shouldn't build lichbane, I was just testing something. I calculated that Lucian should be able to proc spell blade twice with a 1.6 second interval.

My theory was that Lucian E had a 9.6 second cooldown with 40% cdr at rank 4. If Lucian used his E passive Q passive combo, he would knockoff 8 seconds off of his E, leaving at least 1.6 seconds before he could use his E again. Just enough time to for Lichbane to go off cooldown and proc again.

After testing on the practice tool, I realized Lichbane didn't go off cooldown as expected. The cooldown seemed to be more set to 2 seconds rather than 1.5.

What worst about this lichband and the other spellblade items were supposed to have been changed from 2 seconds to 1.5 seconds a long time ago. I think the change was since season 4, and all this time I've been thinking it was a 1.5 second cooldown until actually testing it. I think this reflects very poorly on riot part as this was part of the trade off for the lichbane nerf off 75% AP to 50% ap. The idea was it did less damage but could proc more often. Turns out that wasn't the case. It just plain did less damage for the same 2 second cooldown.

I know it doesn't seem like a lot, but when you are dealing with late game, 0.5 for an extra 50% ap on your next auto can make a huge difference.

Not to mention its very misleading for players who want to use lichbane more for sustain AP damage rather than burst.
