1. Numbers can lie as my post proved.2. Comparing the brimstone and floor scorcher it is clear that from the numbers in game that the scorcher is clearly better than brimstone in nearly all circumstances. But i'm not here to prove that brimstone is best just useful.3. Brimstone can still be used since two floor scorchers just apply the same effect twice and they can't stack. Neither stacking damage or combo so putting more than one facing the same place is a waste. In trap room you will probably need another trap to place. So v. tar and floor scorchers won't make a good trap room by themselves. So brimstone would make a great addition.4. Just looking at the Brimstone working it is clear that 0.13 charge regen is wrong. Since just looking at it and counting for 7.8 seconds it is clear that it fires more than once.
