TFT: Elementalists not getting double mana

with 3 elementalists they are not getting double mana with having 3 of them. I just watched Brand and frost lady, and they gained same amount as if they were alone.

I will say, if it were double mana, it may be to strong, but it should fix before finding out. Brand is a 4 cost, and atm he's super under par in comparison to others, but maybe with this bug fix, he will be much stronger....and worth the 4 spot.
