Yes it increases the duration of all control spells and increases knockback with repel (have not tried Ice Storm, but I would think so).
Oppressor specced CWs with control bonuses can do serious control, especially against those without Transcendent Elven Battle enchantments. Against those with TEB the effect is noticeable, but still very slight.
My mounts all have control bonus and I have valindras crown set and switched from MoF renegade to MoF oppressor today and I now love pvp style. I could easily keep 2 to 3 people at bay on a point in domination. I don't totally understand how the set works and control bonus in general works though. The stats I have on control bonus is only 579 but witb vals set thats 15% more and with wisdom bonus another 11%. Today though there were some people I could hold for a solid 3-5 seconds.
