Enchanter stun mechanics

[digitz80]

Do enchanter stuns stack, or do they overwrite? My enchanter doesn't have an 8 second stun yet so I can't really test it.

Basically wondering if color fluxing something that just got hit with color skew is actually
detrimental since the flux will overwrite it, or if they stack and exist at the same time.

Or another way to look at it, in AE groups, if one chanter casts Skew, another Flux, and they land at the same time, are mobs stunned for 4 seconds or 8 seconds?
