I have tried this hammeri n PvE and its amazing for the slower bosses. In PvP i had a weird experience against it. In a 2 vs 2 whenever i got hit by the guy with Leod's with R1 i could not roll out of the second R1. Also i could not roll out of the weapon art although the page nodes state that it should be possible to roll out form the second hit from the WA.
Now i tried Ledo's myself and my R1's never connected into second R1 and my people always rolled out of my second WA hit. Was the one guy where everything connected and where i couldnt roll out cheating?
