A lot of the time it's less of train X until he dies, but switching from X to Y with burst and CC.
For example when a bunch of DPS are beating on a healer (say a Rsham) in a Rated BG for example, what is happening? He's got beacon from a freecasting Pala, and full blooms from a RDruid all the while kiting into a better position making him harder to connect on. Of course he is going to feel unkillable.
But what if the shaman is put into a stun when the druid gets feared and everyon swaps onto the paladin? If neither of the healers trinket, it's very possible for the Paladin to bubble right there or even be globalled. The same concept applies to healers in arena, you just have to set it up, not train mindlessly.
