First off, if you are premading; a "big group" should never even touch you. (unless of course it's a stealther). Your team should be escorting your or controling the other team so they cant get to until you've at least made it to roof or top on tunnel.
Lay of Hands can only be used once or twice in a bg, that's not enough to automatically make paladins > rdruids @fcing.
As far as "staying out of those battles" Rdruids are best at that. They can outrun anyone on foot(other than other shamans and druids) while prot paladins won't be able to out run them at all.
And stereotyping that rdruids out run healers is out of the question. A good rdruid knows when you need your healers next to you. Hell, a good FC in general should know never to LoS/outrun your healer.
Not trying to see hostile, but a good rdruid will always out play a prot paladin unless(by luck) you fight a team that has absolutely no one who can silence. In that scenario, a Flash of Light spamming prot Paladin would definitely be better than a rdruid.
