wizards are really overpowered... i bought chakona and the rest of the game became a cakewalk because both his units have such great coverage... one of them with a snare. all i really did was pump magic use every time he leveled. if there were any strong vs cold rounds he'd still be able to beat a lot of them, maybe with the help of another neutral element helping him.
hero selection is a big gamble beyond picking at least one guy who is the right element. chances are the level is full of fliers too, which means you have to bring someone who has ranged units AND is that element. even then you can get screwed by a horde of walkers around if you dont bring melee that are strong against that unit. everyone else is a gamble and the fact the level disappears afterwards means theres no way to prepare for it. annoying.
kinda interesting but there isn't much strategy involved. ranges are really short and mazes are hard to cover so all you really do is grind until you can one shot the mobs and then stack all your towers up because of the high number of aura abilities. i see potential though, if you cap tower levels per stage and make the game more strategic.
one thing that would be useful also is to have a DPS meter to rank the towers at the end of a stage or something so people can see how well their skill build is going.
also the whole shieldmaidens having passives and no one else having them thing hurts it a lot. with the micro system in this game id rather just grind out levels and use two simple abilities than level up a bunch and try to use them all
