Landscape is the key, unless you use it well he'll just keep the clicklock on you and eventually you'll die. Get to an area with a lot of pools, bushes or if there's a wall box use it's cornors. For instance, if you teleport to the other side of a pool, the pally will usually have to notice it, manually move to the other side and click you again, during this time you can attack. Just for the record, it sounds easy in writing, accomblishing the landscape use is quite another thing, takes a lot of pratice.
Yes, the knockback on the charge is what will kill most, after being knocked back the pally will continue click-lock meaning that you will keep getting charged. Even with high FHR its still quite hard to get out. With high damage chargers, you can only take 1-2 hits. Chargers are hard, and remember its better to take a charge when you are close to a wall so that he can't continuously use charge.
