I saw something about blizz perhaps removing paralyzis from the shaman elemental tree. This could be a good alternativ:

notice the 15 min cd, that would by all right keep it from being used in arena since that would be potentially very OP.
Im also avare tht this might be considered a tradeoff since elemental shamans really could use some pvp buffing but you gotta admit its pretty cool xD
