As Sonya said, Hallowed Ground isn't used for its damage. It's used for both the immunity to procs and increased armor while standing on it, and also for the Radiation procs that enemies may recieve on every tick of damage.

As for not needing duration on Oberon, duration increases the time enemies stay blinded by the blinding effect of being near Reckoning, and is also inversely proportional to the duration of Renewal. That means that with more power duration, Renewal's passive regen lasts for a shorter period of time, but since the amount healed is the same regardless of duration this means that you will heal a larger amount of health per second. Lastly, this isn't really anything special but duration also increases the time Smite's projectiles stay flying around in the air, which can increase the chances of them finding a target to hit if they haven't yet, netting you more Puncture procs which can prove useful for survival.
