The scattered variant was removed, it traded reduced range for an increase in damage, current Pro blaster Ion Cannon 136.5 damage (these are off hand estimates I may be off by .1 or something). 1.6 best Pro blaster Scattered Ion Cannon 150.5 damage. So far the base damage was reduced by getting rid of the scattered variant 9/10 tankers used scattered variants.

3 separate passive upgrades totaling to 30% extra damage were removed so the Scattered Ion Cannon could deal almost 200 Damage a shot

There was 1 passive Upgrade that increased range by 15%

There was 1 passive Upgrade that increased blaster zoom by 10%

Active Heat sinks have been removed they allowed for tanks to fire for an extended period of time I believe it was 57% longer and was easy to fit, damage mods are now active and high slots a substitute for heat sinks but are extremely hard to fit usually requiring a CPU upgrade so you lose tank.

Blasters are also pretty awful tank vs. tank sure I kill dozens of militia rail nubs who don't know how to fit their tank but if they know what they are doing it is very difficult to win a tank battle

Please don't double nerf our blasters I do agree they require a little bit of tweaking I would personally like a slight damage reduction 15% max for increased hit detection hit detection is (often delayed so I hit you 2 sec later you receive damage, ever get hit behind a wall it's likely that you got hit before going behind the wall it just registered when you ducked behind it, or I will flat out hit someone 3 times in the face and they don't drop a single hit point of shield) I would also like a range reduction we do shoot a "little" too far for a close range weapon.
