Honestly I like to take both corrode and loot. Corrode takes care of all the brews and wish junk running around, loot lets me get those tasty tinderboxes and bone cloaks. Although I'm don't consider myself good in any way shape or form.
This is actually a really balanced spell imo. The dmg is negligible, you have to walk in it's aoe to be ensnared and it's price is pretty high. It is great in a lexicon bg and if you are running a lot of equips yourself than yes, it is annoying, but other than that any KF player worth his salt will use brambles over this spell in just about every other bg.
