Arena Skill vs Normal Skill proc

So I found this link : http://www.fantasicaunofficial.com/t9709-arena-skills

So how do the arena skills work with the normal skills?

Say, Selina with Knockback and Backstab, does one just come out randomly? Or does Arena skill just override.

What about an unit with Offensive and Defensive skills?
Aksana attacks and uses Slow, but when defending uses Ironwall?

Arena skill overrides, as far as I know. Never seen a Bajardo doing knockbacks during Guild war event.

Arena skills override the Normal Skills, so in the example of Selina's Knockback skill and her Backstab Arena Skill, once she is deployed in the Guild War event, her Backstab Arena Skill will only proc and her Knockback skill with be ignored.

The same goes for Aksana's Iron Wall. Her Slow skill will never proc during a Guild War or Battle Arena event.

During normal quests and certain other events, Aksana's Slow skill and Selina's Knockback skill will proc, while their Arena Skills will be disabled.

And... if we ever get another colosseum event... They use normal skills and not arena skills.
