It's not support's job to protect you from skill shots.
If you really can't dodge skill shots, you should rush 
If I'm using 
, I'm not going to dash to you to block a hard CC skill shot like
that's a suicide dash.
If I'm playing
the reason my spell shield came out late is because I expected you to sidestep the skill shot. In my head, if I shield you on a dodged skill shot, it has a longer CD than the poke abilities that get spammed so now we're both more vulnerable.
As
I'll only heal you below 40% threshold because keeping up with the amount of times a skill shot hits you means I'm burning my health pool trying to save yours.
Lastly, the tanks aren't tanky at level 1, so also not going to try to body block a skill shot early game just because I'm using
.
If you don't have jukes,
and healing/lifesteal runes are your bestfriend.
is better but even then it will slow down your item spike unless you are playing vayne or an onhit adc. Building
or getting a cull or 2 solutions to help against this issue of the adc getting caught (as the adc anyway). Some go double dorans blade but Imo that slows down you spike too and it is early focused, it can work but I prefer
to it since it is technically a free item once you get 100 minions.
