INT working as intended.

You don't have to exclude criticals when evaluating the impact of an attribute on skill damage. But you should do each test at least 500 times to minimize the randomness from criticals <.<

Ya hopefully the volume of tests done would drown out the spikes from crits to an acceptable level. In any event, while the data presented might not be done in keeping with the strictest scientific methods (or methods that are satisfactory for the academic community on these forums, all of them being PhDs in MMO Maths) it still illustrates and reinforces, even if in a limited fashion, the notion that INT and the damage one does are positively correlated per what SE said about the stat.

Thank you to the OP for taking the time to post your results and conclusions.
