Speed Infusion 11 does not work

Just because you told us it doesn't work doesn't mean it's proof. Numbers, dude, numbers!

EDIT: Your thread title is misleading too. I came in here expecting to see claims that there was absolutely no booster happening at SI 11.

Still, getting Speed Infusion to Level 11 isn't a complete waste for a few reasons:
1. You'll already have it to the desired level when it finally does work.
2. Other classes still get the boost from 11 SI.
3. You don't have to use Wind Booster as much and can just macro your two boosters.

Basically I did the 100 attack test, and it took the same amount of time for both boosts to reach it. (4X seconds?) Let alone I don't see any difference when training. Just saying this since I seem to be one of very few people who've actually tested this.

Then name your threads properly and don't post things that most members of this forum know to begin with.

Wrong.
