They have same costs. And we have a wm like Thalassa, totally out of control, who can keep the enemy team unable to play for a whole fight (the new cc system was supposed to prevent this, right? Lol) and needs an obvious nerf.

Then we have another wm like Zahra, with skills that are a joke compared to other this one.

There should be some kind of balance, as I said the cost is exactly the same.

The Warmasters are fine as they are, I think. Of course one is more powerful, or has a more obvious purpose than the other, but the same is true for VIPs and Nemeses.

Thalassa needs a nerf though, she just is a big fat joke and should be renamed 'Squid the Win Button'.
