Paladins excel at handing out saves with bonuses, they're among the best at it. I've been playing a currently level 14 Kalashatar Wis/Cha Paladin and I've saved so many people with my free saves and bonuses it's not even funny.
Healing, however, is a different story entirely. Lay on hands isn't really always healing. When you're dealing with several opponents the paladin can have a hard time stopping them all, so sacrificing one of your surges to heal someone is really more like retroactive defending, which actually lets the ability slot entirely into the defender roll. I've mainly used it for emergency heals and when people are getting low on surges (the DM is pretty ruthless and effective full rests can be in short supply).
The striker paladin build looks a very potent, however. I made a half orc Str/Wis/Dex paladin as a backup if my other guy dies, out of curiosity. He gets a 4W dailies right from level 1 (and a good one at that, especially at higher levels) which is pretty good with a fullblade. Took pit-fighter as my paragon path, so at 14th if he wants he can do something obscene like add 2xStr and 2xWis to damage a few times a day. However he's lacking on the 'ignore me and do absolutely nothing' aspect of my current PC, mostly because of the Hospilitar path, which really pushes you both towards healing and being someone monsters can't ignore.
