Caustic Gas Traps

I made a post proposing some changes that I think would help buff Caustic up to the same level as other legends, give it a read if you have some time.

As for this post, here's a couple points:

1. Caustic Gas should still blind all players who are caught in it, including teammates. Changing this would also mean Bangalore's smoke would also need to be more see-through or there would be a shift in legend balance. The fact that teammates don't get slowed down nearly as much anymore is already a great change towards how gas effects teammates.
2. The gas traps have a lot of gas in them - they'll be pretty big bois. Also, you don't want the gas traps to be smaller. As a Caustic main, I can even see that would be bad change which would just make Caustic more of an annoyance than he already is. My proposal was to simply make the traps harder to deactivate. 
3. The gas damage currently is in a fine state. 1 Gas Canister can deal 99 damage to a player - if they stay in the gas for the full 12 seconds. My proposal was just to make it more difficult to escape the gas by having the gas range slowly increase over time.
