An agi build doesn't necessarily need to lose out on much str now. I go 24/24 with 2 IF. It does more damage than yours but still dies in roughly the same amount of hits, maybe 1 hit if its low damage. Plus with agi you can reduce the damage you take by moving away from a hit or force glances. I think IF is still a bit of a waste of stats/skills
I have maxed out my IF, in a good round i can tank insane amounts of damage, upwards to 10 hits. I honestly think IF is overlooked, and 1 point of athl/ps can be overrated for what you miss out on. I will respecc to a minmax balance build soon to see the difference, but so far i actually think str is slightly stronger than agi.
Also balance builds were always the best, and thats how it should be since then both attributes are equally viable. And atm i think theres just as many agi based as str based players.
