for the regular tiles. i have about 6 4* and 1 5*, the classes are split mostly evenly. many of the 4* are below lvl 20 since i only got them recently. maybe i have to grind a little more. i'm around maurin and other lvl 37 maps, i can beat them but it takes multiple tries. just feel like the difficulty suddenly jumped up around there. i also might be using the wrong techniques. thanks for the various tips.
