It's time to dust of the pink legwarmers, some advice would be great

Well my luck and patience with squishy supports is starting to run out. I find with the exception of sona and karma the rest of my squishy support pool has become far to reliant on the adc to win the game. Trust me all the heals, Shields, bubbles and Janna ults can't save them from themselves most of the time.

So I arrived back where I started in my lol support career with taric the fabulous gem knight.

Depending on the lane I generally runes which contain hp5 and mp5 to combat the poke from say brand and sona, if it's tank vs tank just the usual mix of armour mr and either gold/5 or hp per level.

Builds, generally endgame I go for sight stone - redemption - locket - fh or f fist (depends on the team) - cd boots - usually knights vow if the game lasts that long.

Keystones is where I hesitate and usually go where I'm more comfortable which is with the increased healing rather than the shield with landed cc. This wrong or right?

Any advice would be much appreciated
