The thing with evade is that it gave another option. Because you have the option to 'slip' rather than 'slide', it adds a level of complexity to the game. One of the reasons being that it forces players to make another choice in their skill selection(do I take anti evade, anti block, or one of the few skills that does both?).
Taking out evade simplifies the metagame(presumably for skill balances as well), while buffing anti-block skills. I would frankly prefer they buff the other skills which are less used(the ones that got a buff from the removal) than remove the mechanic. Then again, I'm not the person working on skill balances.
But that's just my two cents
