I would like to have a new shielding cooldown at some point from lv 60 to 70s.

A shielding ablility that not only mitigate the damage, but stops incoming projectile/cone aoe attack/cleaves, if you are familiar with those champions from league of legends: Braum and Yasuo. You take damage anyway, but the attack do not go further, in case of an aoe attack, you leave a small triangular space behind you where the party can stack and effectively be protected. We have projectile attack from bosses, like the lance thing from thordan ex, with an ablility like this the PLD takes the damage like he supposed to take, but all party members who stay in the spot created by the ability are safe.

Could be made like a tank stance on top of ShO that disable auto attack OR add a heavy debuff, a knight that raise UP a big shield cannot move fast or swing sword .

Sorry for my bad english, btw this is my first post XD.
