Shaco bugs

Backstab overrides Stormrazor's proc and completely wastes it. Literally doing more dmg while hitting enemies from the front. R clone doesn't lose Stormrazor's proc, no matter how many attacks it does. R clone Backstabs override Stormrazor's proc and the clone deals 130% crit instead of 200% too. Shiv and IE on-hit/true dmg also gets drastically reduced due to Backstabs overriding regular crits from Stormrazor.
