Your paladin is doing an
extremely bad job. He'd probably do more HPS if he went ret with seal of insight active. I really don't understand how he's able to make holy shock be 24% of his healing done... does he spend 2/3rds of the fight just standing around doing nothing? I also see zero daybreak, which is amazing for someone spamming holy shock and heaing with eternal flame. If he doesn't have the mana to cast holy radiance now and then then he needs to gear better (it's impossible to say how his gear looks like, since he's in prot gear on the armory atm); he should not have mana issues unless he's doing something extremely wrong.
Here's out log for this week, demonstrating that it's quite easy to do upwards of 80k HPS as a very average-level paladin (Simulacrum is me):

Paladins are extremely strong on Garalon, anyone who tells you otherwise is lying, and statements like "it's relatively difficult for a hpally to compete on heals due to short range of holy radiance" are gibberish. Radiance is about HPower generation and daybreak procs on these fights in 10m anyway, not about the healing done.
