Don't worry- BAR will remain overpowered and people will continue to flash their wallet in place of acquiring PK Skill.
Bullet spread doesn't lower skill requirements.
It's a preference-- a variable that makes one gun different from another. There are advantages to having spread, and there are advantages to shooting straight.

Era PC at it's finest competitive days had guns with spread; and some of the best PKers preferred the straight-shooting AK47. It wasn't until they released guns with low freeze that skill requirements started to fade.

Freeze is the #1 gun variable that stunts skill requirements. If somebody knows that their movement will not be impeded by firing a gun, they'll take less care of their shots, and therefore never recognize the importance of skill; as they won't need it under such circumstances.

Even a gun with a high rate of fire can be tamed if it had a high enough freeze to counter it.

I define "skill" on Era by fully mastering these three factors:

• 1) Bullet Dodging.
  Weave in and out of opponent bullets.
• 2) Timing your shots.
  Fire the most effective shots for the least vulnerability(freeze/reload)
• 3) Movement.
  Move in a way that #1 and #2 can be best utilized to achieve victory.

Unfortunately, iEra's current walk speed doesn't give bullet dodging much of an influence, and guns like the Souizen give users very little vulnerability upon firing a shot. The slow walk speed and the lower freeze are just begging people to spam their guns, because it's highly effective.

If you want skill requirements, start by improving the walk speed.
Give skillful players a chance to weave in and out of spammers' bullets.
