- The gas as it is does way to much damage, In my opinion the gas should do no damage or minimal damage.
- Since this is a team game and all the gas messes up as much for the team as much as for enemy's its not nice to have a caustic in your team.
You can't compare this with Bangalore smoke or something because that skill is easier to place and control.
Remove the gas slow effect on teammates and give the teammates a little more sight in the gas then enemy's.
This way the caustic and the team get a advantage in the gas, But still have to shoot the targets.
While your at it maybe even let teammates heal in the gas or something or take less damage in the gas ( Be original ).
maybe even in a liniair time line remove sight from enemy's that stand in the gas for to long or get to close to the center of the gas or something.
I think this way you will make the gas traps worse for players who mindlessly drop/use it to deal extra damage and a lot stronger for people that effectively use it.
I believe this way you invite more and better team play and deeper skilled play.
And less mindless dealing damage with ult and traps and good placement will get rewarded.
Also good teammates will be able make effective use of the gas this way.
Also i understand above described is rather overpowered, So remove the fortified witch was a joke in the first place.
And let the usefulness of his skills be a reward for playing a legend with a larger hit box.
