The main reason for this poll is to make it clear to all people who play or plan to play zealot about exile vs other shields. If you pick other shields as being better, then there is no reason to express hostility toward people who use exiles. If you pick exiles to be better, but bm, then you can choose not to duel exile users.
I know that you can use life-tap wand, but I've never seen anyone uses it effectively. Akara is working too hard for life-tap wand to be effective.
EDIT: after all, we all want the most effective setups. If you think your opponent setups are better, but bm, then don't duel them. Similar argument can also be made about hs-prebuff switch vs cta switch. (Please note that this thread is not about temple)
