how much does agi affect avoid and crit

[matai]

<DIV>idk if its on the forum too many to sort through .. im a lvl 57 bruiser going on 58 and i can self buff my agi to 433 agi not bad on my own i dont think.. but my avoid is the same as people who are lower lvl than me with under 100 agi than me as well .. off buff i run at 63.5 normally ...(idk if that exact but its within 63%-64% on offenseive and 66%-67% def stance, since skill points rise too often during xp sessions)... also i see that i sometimes have more agi than bruisers higher lvl than i and they have more or the same avoid as well ... ive selected the def parry and deflection class and racial upgrades that have come my way .. so how much DOES agi affect avoid it thought it was a primary for it to an extent .. also thoguht it affected crit chance as well? but i have a tab to check my crits see how often i hit with them, and i rarely see them happen. pls inform me as to what im getting wrong here ty ..</DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Mataive: 57 lvl bruiser 40 lvl tailor</DIV> <DIV>Server: Vox -pvp </DIV> <DIV>GUILD: Chaos</DIV>
