i wasn't using shield alot since i've decided to try to solo NMs.
in a single 5min fight with an 47 level NM (Old Six-Arms) i blocked twice!
this makes me think, that using skills like Aegis Boon useless, simply because the skill timer runs out before i was able to block.
idk, maybe on gladiator block rate is higher, but i saw my friend gladiator complaining, that after the patch he is struggling to stay alive tanking ogre in level 45 dungeon, when before the patch it was no problem to him.
