Can we make them suck less?

>Can we make them suck less?

For example: Explain why you think they suck. Explain how you would like to see them changed.

In general transmuter spell cost is so high in group vs group fights they run out of juice long before the fight is over. They don't work all that well, specially at hero lvl using metabolic spell in pk is just wasting mana. In general vs 3-4 people just to get them slowed down I have to cast it multiple times. Considering they are useful in extremely dangerous situations and how much mana it costs. I would like to see them work a lot more often.

I talked it over with Valg & Nep, and the hard part about these spells is balancing the "awesome gankiness" of something like mass metabolic slowing. I'll take a look at success rates, but I doubt that they will get much more than tweaked.
