I have been using target shield player instead of anything else for warzone I make myself the shield. It helps allot. I usually am on the def allot so I don't have to move around alot, but when my 4 chars park something like in alderan, no one seems to bother me due to the fact it is annoying to urooot 4 pvp battlemaster sorc's. I have all the characters half both dps tree's so I can spam insta lightning, but my healer also is half heal / dps and so far it works out great. I shield up then zap zap, all heal if needed 1 target, if someone dies I rez at end of battle. Should be a key binding for target shield and all the symbols u can put up.

P.S. It works great for PvE also, I have two click bars setup one for the cc of a shape, that way they will always target it themselves and i won't have to waste the time. Also works good for healing if you want the shapes over your characters heads.
