I personally think that we already got magic in movement implemented by weapon enchantments. I would prefer to make the dot damage increase over time, reaching a level slightly above double nuke damage (dps).
This would make dots an alternative when link stability is not the issue (ie. your target is below your elemental level). Using dots would take away your freedom to drop in a heal or do any other actions while channeling damage. But it could be an alternative in many situations where the best option is stupidly hitting one key over and over again now (and almost falling asleep). It would require much attention to deal dps above the double nuke level. And it would probably deprecate the cast breaking exploit to increase dps.
