I'll answer for him David, there were a few motivations:
1) to sound cool and edgy
2) to make his guild look better
3) an attempt to condescend me since his feelings got hurt when I pointed out how bad his guild got rocked
4) feelings might already be hurt since nobody in guild can handle me in spars including the precious Sara
But cheapshotting and trash talk are pretty much my whole schtick therefore his attempt at condescension has failed.
