Regarding the notion that Patch 2.3 won't make Animus easier:

It was stated in live letters that both 2.28 and 2.3 would increase the rate at which we gain Myth, and any increase in Myth gathering makes the Animus easier

Regarding the "not using IV's makes the Novus crappy!" argument:

Here's some actual facts on the matter.

We know that there are weights on each stat as compared to a class's Main Stat(STR, INT, MND, whatever). However, Weapons have a stat unique to them: Weapon/Magic Damage. This stat is considered for nearly every class to be worth between 8-9 of your Main Stat alone. With the amount of it that a i110 weapon provides, it combines with the literal amount of Main Stat on the weapon to provide over 95% of a weapon's potential for damage. Secondaries on the weapon, when taken alone, will usually provide less than 3% of a weapon's potential damage even if they're fully optimized. That 1% crit rate you're debating about? It'll make your weapon do 0.1-0.2% more potential damage.

What this means is that secondaries matter less on a weapon than they do on pieces of armor. It's the one place you can put stats that are useful but don't add damage without making that overall equipment slot useless. So, I'd say throw that Parry, Piety, and Accuracy on the weapon. As long as you have the Weapon/Magic Damage of an i110 weapon, the secondaries will not make or break it.
