in my playings I have come to find that each type of summon scales with a better power bonus as you go down the page, as i should be, unfortunately there is one exception to this rule and that would be the Behemoths, they give half of the power of the one before them, the Leviathans, so for the time it takes to get each tick you are not getting your monies worth, they are literally not worth investing in, this should probably be fixed so that it scales like everything else, also the Titans and Leviathans give the same amount of power per tick at their respective power cost levels. So fix the scale issue with the last 2 summons and this will be a lot better. :D
