SWG Credits players can save your other shield for when you need it.
The simplest way to get around this is to use your PVP trinket to break out of them. But you can only use it once every two minutes. When the enemy sees that you have shielded yourself they will usually stop targeting you and leave to fight your friends. By the time your shield is down they will be busy with your friend and SWG Credits players can save your other shield for when you need it. Fortunately nearly all crowd control will break if you take damage and paladins have a special trick for causing damage to them. If you cast Blessing of Sacrifice on one of your teammates you will take a little bit of damage every time they get hurt and usually it is enough to break out of a crowd control spell. When using this tactic though keep in mind that the damage you will be taking for your friend can stack up quickly and kill you if you are not careful. On the positive side you will be helping a friend stay alive longer.
