Ok now I realize that poison is a mixed bag, some love it and some don't. But, I think we can all agree it really sucks on MMs.
The small radius on powers and frankly it's so mehtastic that when I make a new MM I don't even see it on the power pick list.
So minor tweaks.
Toxic DoT to all powers.
Alkaloid a splash AoE heal.
Toxic Cloud, a toggle of -res and toxic DoT or maybe a AoE in line with Tar Patch/Ice Slick, etc.
And increase the freaking radius of powers to be more in line with Fenders/Corrs.
Now, now before everyone starts down voting it and getting all pissy. Take a breath and remember its a Suggestion.
So maybe when y'all get around to giving some love to Mercs, maybe some kind of love for Poison.
