No worries they are going to make mini gameplay on each summon so it feels different for new ones. Like shiva enkidle can be a long cast spell while the normal one is instant, Levi is a instant cast spell on enkidle however cast normal spell will be 1 sec or something finally ramuh can be gcd skills can hit meh but is ogcd one hit like a truck. I'm sure devs will spice it up our gameplay on next expansion meanwhile keeping our not so much button to press playstyle.
