point 1: don't get absorbed into the 'tank zone'.
you know. the one where u just get hit and regen hp all back anyways?
point 2: cuz that's not how u play squishy supports.
u stay back. and let your carry do all the work. and provide them with backup.
for the 3 AP squish u pointed out
i hope you're running armor runes or something cuz she got nerfed hard over the past year.
but same as always. she EXCELS in poking short ranged ADCs. like Vayne for instance. just walk up and Q a few times.
post-6/ you're a walking AoE stun/dance machina. refer to point 2.
she works best in a team that can engage freely. so u have options to ulti for more AoE wombo potential.
her W provides beautiful CC it's just short from an actual stun. max it.
she also pressures invis champs cuz her shield reveals stealth'd units if they are struck before entering stealth.
the icon of point 2. refer to it.
and also land your Q in lane for TROLOLOLOL infinite HP sustain.
