By my point of perspective ,
Indeed backfire might need some kind of fixing .
But definitely the sudjestion above isnt correct on the way of thinking / calculating .
We cant receive a 3.500-4.200 hps physical mech as the average rounder phys like was mentioned above.
A rounder phy/heat/en is arround 2.700-3.000 hps .
On the side , backfire values differs from type to type , and phys have the most .
Note : physicals danages arent ~400 plus , but ~300 plus
Also , lets not try to take away phys mechs advantage wich is the damage output.
I wish the future changes will be really fair for all the elements , and to not get on the trap to favour one type .
So far the backfire values looks fair to me in general , perhaps might need an udjustment on specific weapons like scopes for example .
