INT working as intended.

To the comments about crits:

If you consider crits a problem in this test, just look at the crit damage, which is calculated separately. You will obtain roughly the same numbers in % increase dmg.

Yes, numbers will roughly the same for crit, Thunder/Thundara crits will always be around 30% more from the average.

Thundaga is a bit tricky because it has 'increased critical damage' in combo bonus, seems to be 60% more from the average Thundaga, no idea yet if INT increases the critical bonus.
