For a time, I've been recently reading some KFM posts on other websites that compare how the auto-attacking speed is with the two corresponding keys, LMB and R. This also includes the common 3RF combo for CC'ed enemies. Some say the LMB is faster, other say the R key registers faster and thus attacks faster. I just want to know, and if so, change my keys accordingly. Faster attacks = faster combos after all XD. Help.
