Kinda sad that Thornmail doesn't "Reflect" Damage on TFT

I've tested having 3 Thormail using the Dragon Comp so that my Shyvanna would take no damage, reflecting 105% of all Auto Attacks while also being immune to magic damage. Instead, I was disappointed to see that Thornmail doesn't "Reflect" damage, rather, it inflicts 35% (105% in the case of 3 Thornmail) of the damage taken back to the attacker. This does not reduce damage taken, nor does it fit the term "Reflecting". I suggest rewording Thornmail to say "Deals 35% of damage taken back to the attacker" or something along those lines.
