Honestly, Blitz isn't for everyone...I've had good success with him, though.
I play with an ADC that likes to play Kog, so I've played Nunu as support probably more than most. He is still my favorite support, even without a Kog or Vayne to lane with. Rank 1 consume allows him to take harass in lane and soak for your carry, when you proc his passive you get free ice ball harass, and by maxing bloodboil first, you almost always win trades with any decent ADC. That buff is SO incredibly strong, its basically a free PD worth of attack speed. Also, keep in mind you can channel your ultimate in the brush where the enemy cannot see it...your carry should exploit this for easy clean up kills.
Janna is one of the highest skillcap supports simply due to decision-making with her ultimate. Like Anivia's wall, you can seriously screw up a team fight if used improperly. It is hard to describe in short how/when it is to be used, but here's a super-basic video (I wanted to find a better one with less annoying narration, but time is short, sorry.):
Her shield should always be maxed first. Its like a free BF sword at max rank and allows for extremely advantageous trades when used in conjunction with a rank 1 tornado knock-up.
I'm not all that familiar with Lux/Zyra supports...I dunno, guess they just never appealed to me.
Lastly, just to make sure you're privy to this information - I itemize and rune-page my supports all basically the same:
Armor reds
Armor yellows
MR/Level Blues
GP/10 Quints
Items are almost always Philo stone, rank 1 boots, HoG, then directly into Aegis. Once that is finished, you can then make a Shurelyas + locket, then go ahead and grab your T2 boots. Of course, you should be buying as many wards as possible every trip back and communicate with your jungler on oracle purchases.
small edit: I'm unfamiliar with the new items as I haven't played since early October.
Good luck - I find the support role to be the most rewarding by far, but can be extremely frustrating with a shitty ADC lane partner.
